Oh, excellent catch! This bug is only present on lucid, as newer
Ubuntu/Debian dists all have this symlink in r-base-core. Our package
tests didn't notice because we test all .deb files in one run and as
the first package in debian/control uses debian/postinst, the symlink
will be there.

It's a bug in r-base-core which should really be fixed there, but I'm
not going to try to get it fixed in lucid, so adding this symlink
workaround which will only trigger on lucid seems appropriate, while
an rpath would be present in packages for all distributions.
I've added your patch to the plr package. It's rebuilding atm, I'll
promote the packages shortly. Thanks for the report!
