What does "f77 --version" state? Is this really g77?

Bummer. It looks like you did not in fact make the mopac executable.

Further confirmation that mopac did not build.

Do you know that g77 is properly set up on your machine? Can you compile
other fortran programs there? This is the first time I have seen g77 fail
with this version of the mopac code.

If you don't see anything, try this:

cd $ACHOME/mopac6/src
make clean
make >& make.out

And look at the entire "make.out" file to see if there are any other errors.

...good luck...dac
