I finally got a response from one of the core R developers: "libR is 
GPL-ed, and that is unlikely to change" -- so I guess gborg it is :-(
(not that I have anything against gborg ;-))

Before making any release announcements, I'd be interested in feedback 
if anyone feels so inclined. The source is currently available here:
http://www.joeconway.com/plr/plr.0.1.1.alpha.tar.gz

The documentation, including preprocessed html, is in the tar ball. I've 
also posted the html docs here:  http://www.joeconway.com/plr/index.html
From the README (more or less):
-------------------------------
Installation:  Place tar file in 'contrib' in the PostgreSQL source tree and untar.  Then run:
    make    make install    make installcheck
  You can use plr.sql to create the language and functions in your  database of choice, e.g.
    psql mydatabase < plr.sql
-------------------------------

In addition to the documentation, the plr.out file in plr/expected is a 
good source of usage examples.

PL/R should build cleanly with PostgreSQL 7.3.x and cvs HEAD. It was 
developed using libR from R 1.6.2 under Red Hat 7.3 & 8.0 -- I've not 
tested against other versions of R or different OSes.

Please let me know how it goes.

Thanks,

Joe
