I think it's great that you're learning to install from source code. However in this case Bleachbit provides installers for quite a few distros (http://www.bleachbit.org/download/linux
) - did you check to see if yours is listed?
For reasons such as the one John VV mentioned with the install location, I tend to roughly use the following descending priority for installing packages:
(i) install from the distro's repositories (unless I need a version more up-to-date than the version available there).
(ii) install from an installer package (in my case .deb) supplied by the software creator/maintainer.
(iii) install from a PPA (my Mint operating system is in the Ubuntu family).
(iv) make from source code, following closely the instructions in the README and on the software's website.
We can't tell which distro you're using as you haven't supplied this info. You should think of either including it in your profile or signature so that it's readily available when you ask future questions.
