Comment:

openmpi has --enable-script-wrapper-compilers, which installs mpicc and friends as perl scripts, like mpich does with bash.

If we added this option, packages would no longer require openmpi in their build dependencies (they would require perl, though), because the compiler wrappers would be scripts, not executables. I think this would solve a lot of headaches for folks compiling against openmpi.

Weirdly, the pkg-config files don't seem to be installed. This seems like a bug? They are built and correct, just excluded from install.
