I was unaware of this previously, but I'm not surprised -- both systems
(BLCR and BProc) need to do significant mucking around in the kernel,
most likely with the same areas of process management.
This is probably not strictly a LAM problem, but more of a generic problem
of using BProc and BLCR together in a single process. You may want to
contact the BProc and/or BLCR maintainers to see if there is any ongoing
effort to make them work together.

I'm not an expert on how BLCR builds, but it looks like a simple
permissions problem (IIRC, BLCR uses standard Automake/Libtool stuff for
building). Are you compiling this as a user who has permissions to the
.libs subdirectory?
