On debian and ubuntu, it looks like libpq-fe.h is provided by the package "libpq-dev". Can you try installing that package (or equivalent on your distribution)?

Jeff, it looks like he has Postgres installed in his home directory, and the mkmkf.log
confirms that the include dir from the installation is being included in the CPPFLAGS.
@syliang, would you mind testing something out for me? Create a file called test.c
or something and paste this into it:
#!c
#include <libpq-fe.h>
Then run this command:
gcc -E -I. -I/export/home/invantest/tools/ruby/1.8.7/lib/ruby/1.8/i686-linux -I. \
-D_FILE_OFFSET_BITS=64 -I/export/home/invantest/tools/pgsql/8.3.3/include \
-g -O2 test.c -o test.i
and either reply with the output, or attach it if you prefer. Thanks!

Hi Guy,
I know what is the error already. I done a stupid mistake that I didn't notice the machine did not install with GCC. After I install the GCC, pg gem install successful. The error seem to be not reflect the real error but anyway it works. Thanks and sorry guys for wasting your time.

I am having the same problem in arch linux. PostgreSQL 9.5, pg 0.18.4. Trying to require it gives the “incompatible library version blah/blah/pg_ext.so” message.
