You have Fink installed, and the paths are overriding the paths set by  
MacTeX.
You will need to fix this either by removing the line in your bash  
resource files, placing the fink path after your other paths by  
editing the appropriate file in the /sw directory, or removing Fink  
altogether.

There may be other solutions discussed on this list before, so perhaps  
a perusal of the archives would lead to other useful methods of  
dealing with Fink.
In other words, MacTex is probably working fine, but the installation  
of Fink makes it appear otherwise.

Yes, many times on this very list.
