no, there is no fortran compiler installed, but f2c. ./configure without
any options stops with

checking for g77... no
checking for fort77... no
checking for f77... no
checking for f90... no
checking for xlf... no
checking for cf77... no
checking for fc... no
checking for f2c... no
configure: error: Neither an F77 compiler nor f2c found

but ./configure --with-f2c does the job. Maybe ./configure and
/configure --with-f2c search for f2c in a different way?
