what specific non-Windows operating system distribution are you using? ODBC stuff is packaged for most of them. for instance, the yum.postgresql.org repository has it packaged as postgresql92-odbc, available for a variety of redhat/fedora/centos style systems, I'm sure the debian/ubuntu apt repositories have similar.
Currently looking for RHEL 5. Thanks! yes looked into my machine and "yum list postgres*" listed "postgresql91-odbc.x86_64"
But when trying to install, then found the base ODBC library itself are missing and those needs to be configured first on test machine.
