here is one command that solves damn near all of my problems when i can't find something
`locate` (note:: the first time it is run it may say something about ::slocate.db , no such file or directory :: or something similar, in which case , as root run `updatedb`)
eg. `locate httpd.conf`
`locate apachectl`
usually the httpd.conf file is in $PREFIX/apache2/conf (that is, with a default location , unless another was specified during ./configure) and the apachectl is in $PREFIX/apache2/bin directory...anyway the locate command (man locate)
should find that for you...
(oh...another note:: when trying to `locate` something that was newly installed you must run `updatedb` , because `locate` has no clue of what files were added since the last `updatedb` was performed)
enjoy
