Besides mpi being in your /usr/local/bin, is it on the path of your system?

Or, for a more permanent solution,
go to your ~/.bashrc file, find a line which already has some PATH folders
in it, and add the :/usr/local/bin and then just retry the configure command
on a new terminal.
Sometimes I need to use different mpi implementations - apparently at

Don't know what system you're running, but there any many linux distros
which already include gromacs in the repos.
Hope it helps,
