Most likely because, as you wrote, not everything is installed properly on
your platform.

The options you get basically mean that occ will be looking for includes
in ../src (required to include e.g. 'mop.h' and dependants) and ../gc
(required to include 'gc.h' from 'mop.h') and will add '-L../tmplib -locc'
to the commandline of the underlying compiler. This in turn will cause the
linker run by the underlying compiler to link against libocc.a library
found in '../tmplib'. The second '--' is superfluous (a bug in testsuite).

Plase send output of configure and make.
