Do_postgres compilation failed

Hi guys,

I am having a rough road again and I hope you guys can help me out.

I’m on Windows 7

tried to execute “gem install do_postgres” from cmd

compilation failed as attached.

"make: *** [do_postgres.o] Error 1
ERROR: Error installing do_Postgres:
ERROR: Failed to build gem native extension.
Building has failed. See above output for more information on the
failure. "

Any help would be very much appreciated!

Cheers
