This module tries to compile itself with "-lmpi", some systems require additional compiler flags when building and linking MPI applications. If `make && make test` doesn't work, try specifying CCFLAGS and LDFLAGS and LIBS correctly and re-run Makefile.PL. Some systems might be a lot happier with the module if you build a static perl, instead of one which dynamically loads the C portion of this module. You will also need to statically link the Storable module. See the ExtUtils::MakeMaker manpage for more details. ### Working systems SGI - IRIX64 6.5 IP30 - 2 nodes SGI - IRIX64 6.5 IP27 - 16 nodes CRAY - 2.0.5.55 unicosmk CRAY T3E FreeBSD - FreeBSD4.4 w/lam
