[BioC] Installation memory demands (GO, humanLLMappings)

It happens here, too (SPARC/Solaris-9, Sun Studio 8 compilers, 64-bit).  It's
most noticeable on building the metadata packages -- I've seen the R virtual
memory size grow to ~1GB when building *CHRLOC and *LLMappings packages.
Fortunately, my "build" machine has 2GB of RAM.

I routinely build/test on one machine and deploy on others.  However we
are pretty careful to make sure identical OS, compilers, and shared libraries
are installed on all our systems.  The shared libraries are probably the most
critical, as far as R/BioC are concerned.
