If make test worked in the f90 directory, then the f90 functions are
there and can be linked to, because that's what the f90 test is. Are
you sure that f90 built? Go to the f90 directory and do:

make clean test 

In any case, I can't debug without the full picture. Please send me
the *full* output of the following:

make distclean && ./configure && make test

Of course, see whatever environment vars you need.
