[R] Trying to install rjags on Mac OS X 10.5

is unlikely to be correct.  A typical Linux setting is

PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig:/usr/lib64/pkgconfig

and on my Mac the pkg-config files are in /usr/local/lib/pkgconfig and 
/usr/lib/pkgconfig.  Most likely it would work if PKG_CONFIG_PATH is not 
set, so try that first.
