Well, I posted on my own blog a few weeks ago, some software likes to  
use a different one  of the various dot files (.profile, .bash_login,  
etc...)
And when they do, you sometimes get trouble with the path variable  
generated. The different files all have a different precedence,  
sometimes a murky one. The best solution is to install whatever you  
need to install, then go and look in your home directory for any new  
dot files. Open any new dot files and inspect the path stuff. Adjust  
your preferred dot file with the new path info in the order you like,  
then comment out the stuff in the dot file you don't want to use.  
Leave a comment saying what was installed, and why it was commented  
out, then you have it if you need it ever to uninstall something.

Sometimes lots of complex stuff all balances very delicately on the  
PATH alone!
