odbc_fdw

Hi there!

I built the current PostgreSQL 9.1.1 sources under Ubuntu 11.04 (in a 
VMware under Win7).
I followed the steps in this guide: 
www.thegeekstuff.com/2009/04/linux-postgresql-install-and-configure-from-source

It seems to work (I can run the server and connect to it with PgAdmin).

Now I'd like to integrate the ODBC_FDW extension in my installation. 
Sadly, the make file throws errors (no target named "..." specified).
Is there any way to do this in a simple way?

I'm a linux newbie, by the way...

Thank you for your help!
Flo
