what's going on here? the linking flags (-L /usr/lib) should be picking up the
lib - but seem not to?

I don't think you did anything wrong. I had the same problem and the following solution worked for me:
Edit extconf.rb and set the CLAGS and LDFLAGS as this blog indicates

that was it alright. i was staring right at that and didn't see it - odd that
the default system install would be like that eh?
thanks a bunch.

right - what i was getting at is that my postgresql install on this box is the
one that came with the system and i have not installed it. so either the
intial install is incorrect or something else strange happened. if history is
any indicator i probably messed it up somehow

Depends on the system
If it's a Linux you often need to run ldconfig to redo the links after
installing new software...
