Thanks, indeed it works -I didn't think it was make install doing the 
rename.

However now I have another doubt. I installed it in another directory, 
to be sure, and indeed the /lib /share /include directories keep their 
original names -and this feels bad because of clashes. So, I wonder: 
let's say I have a directory gromacs_407 and another gromacs_453. Each 
of them contains their /bin, /lib, /share, /include, /top. Does each 
gromacs know to look in its own correct directory for FF files, for 
example? (so that gromacs_407 looks in gromacs_407/top and gromacs_453 
looks in gromacs_453/top ?)

thanks!
