I am running the 64 bit Fedora 14 distro and everything was running fine but now I am seeing this when trying to run yum:

[root@skye ~]# yum info
Traceback (most recent call last):

raise IOError(msg)
IOError: invalid Python installation: unable to open
/usr/lib64/python2.7/lib64/python2.7/config/Makefile (No such file or
directory)

I rebooted and this does not seem to help (can't imagine why it would anyway, after all this isn't windoze, but someone on another forum with a similar problem claimed that this helped).

Now I did install a bunch of new Fedora updates over the past two days (automatically - presumeably via the yum GUI) so this might have something to do with the issue, but it's also been a month or two since I've attempted to run yum from the command line like this.

I should mention that I added a couple of comments to bug #666826 on the Red Hat Bugzilla - which seemed like a very similar issue, but I'm not sure how distro specific this problem is at this point.

Have you tried rebuilding the rpm database?

Sorry, my mistake.

Hmm, weird. Can you try running yum update --skip-broken ?

yum doesn't work at all.

I thought I'd try downloading and building the latest Python, but I can't even find my gcc compiler...

Damn, your system is messed up.... What did you do? I would plop the fedora dvd in and reinstall...

I am attempting to download all of the rpms neededs to [re]build gcc for Fedora 14 (x64), as it appears that some sort of malicious virus or horribly bad Fedora update messed up my system.

I was able to locate gcc-4.6.0-0.7.fc15.x86_64.rpm and its dependency libmpc-0.8.3-0.3.svn855.fc15.x86_64.rpm on http://koji.fedoraproject.org, but I am unable to locate it's other dependency "libmpfr"

http://koji.fedoraproject.org/koji/s...&terms=libmpfr

..returns nothing.

Does anyone have any idea what libmpfr is and where I might find it?

Thanks

I honestly recommend just putting the boot DVD in and do it from there....

Probably right, so I've mounted the DVD and I'm fumbling around in the Nautilus file explorer on the DVD, but all it seems to contain of any real substance is the isolinux.bin and associated isolinux.cfg, along with (apparently) some boot strap files and things.

I cut the DVD myself some time ago from a downloaded distro, so I guess I will need to boot up to this DVD and enter repair mode or something?

(please don't tell me I am going to need to reinstall the entire system)

Pretty much... You can boot the DVD, and reinstall the system, preserving your home directory.

On second thought, that's too risky - especially since I'm dual-booted.

Instead I think I'll suffer through locating the rpms I need one by one (the old fashioned way).

I'd rather do this than risk blowing away the entire system.

...so let's see... where was I? Oh yeah, libmpfr.so.4

Oddly enough, I found this rpm and tried to install it, but it claimed that it was already installed.

I'm very close to fixing this now. I managed to install gcc without yum and without having to go searching the internet for stray libraries and such...

first, I was contemplating trying to build gcc from sources, so I first thought I'd check to see whether I still at least had a cpp compiler, so I tried just typing cpp. I didn't have it, but lo and behold, didn't it go and ask me if I wanted it? Sure I said! (well "y" to be exact).

Bolstered by the results of this trick, I tried the same thing with gcc and sure enough - voila!

I was then able to "configure" and "make" my downloaded Python 2.7.1 package, and it made it almost all the way through the last step ("make install") before I hit this snag:
