mpich2 fails to package, the build is fin dough. The build log is located at https://technikradio.org/data/mpich2-1.5_9,5.log (It's to large to upload). It tries to package these files: /wrkdirs/usr/ports/net/mpich2/work/stage/usr/local/etc/mpe_graphics.conf /wrkdirs/usr/ports/net/mpich2/work/stage/usr/local/etc/mpe_mpianim.conf /wrkdirs/usr/ports/net/mpich2/work/stage/usr/local/include/mpe_graphicsf.h /wrkdirs/usr/ports/net/mpich2/work/stage/usr/local/lib/libampe.a /wrkdirs/usr/ports/net/mpich2/work/stage/usr/local/share/mpich2/examples/graphics/Makefile /wrkdirs/usr/ports/net/mpich2/work/stage/usr/local/share/mpich2/examples/graphics/cpi.c /wrkdirs/usr/ports/net/mpich2/work/stage/usr/local/share/mpich2/examples/graphics/cxgraphics.c /wrkdirs/usr/ports/net/mpich2/work/stage/usr/local/share/mpich2/examples/graphics/fxgraphics.f (which are non existent). Please review the build log for further details.
