PL/R install, no pgxs available

Hi Guys,

Have 9.1.3 running with Postgis 2.0 . Trying to add PR/R and getting some
errors about my postgres install. I found some similar messages, but none
with a workable solution for me. Any thoughts are very appreciated.

I am running* USE_PGXS=1 make* in my PLR directory and it returns:

*Makefile:36: /usr/lib/postgresql/9.1/lib/pgxs/src/makefiles/pgxs.mk: No
such file or directory*
*make: *** No rule to make target
`/usr/lib/postgresql/9.1/lib/pgxs/src/makefiles/pgxs.mk'. Stop.*

It is correct, I have no pgxs folder under lib, must less the src and the
makefiles. I have read 35.16 in the 9.1 documentation on building the
makefile for pgxs, but I really don't understand it and not sure it even
relates to what I am doing. (
http://www.postgresql.org/docs/9.1/static/extend-pgxs.html) I can't
understand if I am suppose to create those directories and build up the
makefiles myself (I sure hope not), or install some sort of pg dev kit or
what.

*Here is my pg_config:*

Please tell me any ideas you have. I am at a stand still on this.

Thanks,
