There's a tendancy for R builds to not bother building the sharable
libR.so library.
The key to figuring it out is to check what's missing in library
linkages. Two options ought to be helpful:
1. ldd /u/local/pgsql80/lib/plr.so
2. ldd /usr/lib/R/lib/libR.so
On my Debian/unstable system...
cbbrowne@wolfe> ldd /usr/lib/postgresql/lib/plr.so
libR.so => not found
libc.so.6 => /lib/tls/libc.so.6 (0x40022000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
It may suffice to figure out where libR.so is, and add that directory
in via LD_LIBRARY_PATH...
