It may be that gcc and sgicc (or was it sgic89?) have different
conventions for calling C from Fortran.  In that case, the C library
routines you have compiled with gcc couldn't be found when trying to
link with Fortran routines, perhaps because the names don't follow the
same rules, for example appending an "_".  If you really need the f90
interface, you might have to either compile everything with gcc or
find some gcc flags that made it match what the sgif90 compiler
expects ...
