[R] Installing contributed packages on MacOS X: Solved!

[Prof Brian D Ripley]

KernSmooth does not have any paths `hard-wired'.  But pre-compiled packages
do inherit from the R they were built under, in this case the location of
BLAS_LIBS in etc/Makeconf.  So looks like the problem is with whoever built
the packages: definitely not `in the packages themselves'.

A cursory reading of the sources will elucidate this!
