Compiling a program... then removing it...

So i made a bit of a stupid mistake -- I was compiling Jabberd 1.4, got all the way through and 'make' the program - then I tested out some values in jabberd 2, and compiled it as well as a demo, and then 'make' that guy. I did this because I was going to upgrade to jabberd 2... downfall, it won't run on my server.

Now, I deleted the original files for Jabberd 1.4, so I attempted to upload and configure and install this guy as well... now it errors out. Question is, for someone who's learning his advanced way around terminal bin/bash (I'll go intermediate at best on my code), how do I kill out some of those old installs? Obviously, just deleting the folders of the program isn't all that's needed to be done:) thanks;)

Looks as if I sudo make uninstall, that'd be fine... however, I don't have the original installer... scary... learning rule of linux, track your packages...

That's why RPMs are so nice. If you can't use those always look to see if it has an uninstall script. If not takes notes of what directories it installs files in. A few places to check for remaining files would be /tmp and /home/yourusename. Check for hidden directories with the software's name in in like .jabber in your home directory.
