uninstall source installations
 

lets say I installed a program from source, now I want to redo the installation. Is it sufficient to do a whereis command and manually delete? what is the make clean command? What is the most efficient was to uninstall.

well if you still have the source folder, usually you can go into the folder and type make uninstall and if either a) its not offered or b) you deleted the folder you can check out the program CheckInstall
