Hi Ceriel,
Building VOS 5.0.9 with 'make -j2' succeeded in december 2008.
Now trying with VOS 5.0.10.
After some failed VOS 5.0.10 build experiments, executed were:
$ make clean
$ CFLAGS="-O -m64 -mmacosx-version-min=10.5"
$ export CFLAGS
$ ./configure && make -j2 && sudo make install && make check
'make' without '-j2' finishes the VOS 5.0.10 build process.
I can confirm that this has been resolved in the next release of VOS.
The problem was that the plugin code generation rules where not safe to
be used in parallel builds. It would work on a fresh tar extract since
these files are prebuild and packaged, but a make clean would remove
them, so the next time you did a parallel make it would fail.
