Absent Linux Libraries

Hi there,

I'm in the process of porting Intel's DRM driver testing suite,
igt-gpu-tools,
to FreeBSD and I'm not finding some Linux-specific runtime libraries in the
ports tree.

The two that I'm having difficulty with are
* libkmod
* libprocps

I've tried querying the pkg database using the pkg-provides pkg plugin:
`pkg provides libkmod` returns nothing
`pkg provides libprocps` returns nothing
I have tried different naming variations and none yield results.

I don't want to rely on the Linux compatibility layer for these libraries.
Am I out of luck or am I missing something in plain sight?

Thank you,
Jake Freeland
