What exactly did you set?  You want to be using FC=f77 and CC=cc when
configuring R. You definitely do not want CC=CC.

Look in the config.log to see more details.  This is also a test of calling
Fortran from a C main program.  So it will fail if Fortran cannot be mixed
with C (for example, if CC was set to a C++ compiler), or if
LD_LIBRARY_PATH needs to be set to find the Fortran libraries, ....

I am not entirely sure what `Forte 6.1' is, but think it is a marketing
name for what were SunPro WorkShop compilers.  If so f77 and cc on Solaris
7 are part of our regular tests.
