There are current ready made packages for openswan at:
http://nbd.vd-s.ath.cx/openwrt/packages/

It works with the included gmp.

I have had similar problems. Though the proper way of specifying the headers
and linking information is using the variables in Makefile.inc and setting the
environment variables for LD and CC to include -I and -L paramters.

I had the same problem. Ken, what did you do in the nightly build to fix this?
