This fails:

gln -s "sparcv9"
"/home/maciej/src/opencsw/pkg/nspr/trunk/work/solaris8-sparc/pkgroot/opt/csw/lib/nspr/64/64"
gln: `/home/maciej/src/opencsw/pkg/nspr/trunk/work/solaris8-sparc/pkgroot/opt/csw/lib/nspr/64/64/sparcv9':
cannot overwrite directory
gmake[1]: *** [post-merge-modulated] Error 1
gmake[1]: Leaving directory `/home/maciej/src/opencsw/pkg/nspr/trunk'
gmake: *** [merge-isa-sparcv9] Error 2

I think it's because it must be run only once per architecture, that's
why I initially chose post-merge and not post-merge-modulated.  Is
that correct?
