I'm actually looking for a fortran 90 compiler to run under NetBSD. It
seems that gcc 3.5 has such a beast, so I tried to compile it, but have
already got stuck at the configure stage..

First attempt (in /usr/obj/local/gcc):

/usr/src/local/gcc/configure --prefix=/usr/local/expt_gcc --enable-languages=f95

Result:

checking for correct version of gmp.h... no
configure: error: 
The following requested languages were not found: f95

Second attempt:

/usr/src/local/gcc/gcc/configure --prefix=/usr/local/expt_gcc --enable-languages=f95

.. configure succeeds, but then:

% gmake
echo '/*WARNING: This file is automatically generated!*/' >tmp-c-parse.y
sed -e "/^@@ifobjc.*/,/^@@end_ifobjc.*/d" \
    -e "/^@@ifc.*/d" -e "/^@@end_ifc.*/d" /usr/src/local/gcc/gcc/c-parse.in >>tmp-c-parse.y

gmake: *** No rule to make target `../libiberty/libiberty.a', needed by `genmodes'.  Stop.


Any thoughts on what to do next? I note that libiberty appears in
configure.in:

  *-*-netbsd*)
    # Skip some stuff on all NetBSD configurations.
    noconfigdirs="$noconfigdirs target-newlib target-libiberty target-libgloss"

Is that relevant?

Cheers,

Patrick
