[Rd] libgfortran misplaced in Mac OS X R install (PR#14226)

[Simon Urbanek]

This is not an R bug so please don't abuse R-bugs. It is likely a bug  
in the way OpenMx binaries are distributed by someone (you didn't even  
say where you got them from) - OpenMx is not even on CRAN so take that  
to whoever gave you the binaries. On CRAN we use the correct paths.

Cheers,
Simon

Those are very old posts and those were temporary issues in the CRAN  
build system that have been promptly resolved.
