When Gromacs is installed, the location specified with --prefix= on  
the configure line is compiled into the program.

At runtime, we do the following to find library files:

1. First we look in the current directory for files
2. Then, If the GMXLIB variable is set, we look there.
3. Failing that, we check in the default install location compiled-in.
4. Finally, if nothing else works, we try to find the full path to  
the binary you executed (either it's in the path variable, or you  
gave a full path when running), and look in the same tree for a  
gromacs installation.

Thus, if you used fink to install but Gromacs can't find the  
libraries my first bet would be that --prefix wasn't set correctly  
during compile.

Cheers,

Erik
