% mpicc -showme

I had to include lam_totalview to get rid of some error (probably
missing symbols). My ldflags and ldlibs for linux didn't include that
stuff, but I didn't need to make a dynamic library (it was static).
After removing the two libraries I still am getting the following for
-bundle:
ld: Undefined symbols:
_environ
And for -dynamic I get:
ld: Undefined symbols:
_main
