30.1.3 Linux, Redhat 7.2

These old versions of Linux only have v1.5.2 installed in /usr/bin. As such, you need to install a new version of Python 2.3.4 as described in the section below on building Python from source. Python-OEChem for this platform was built using gcc 2.96 as found in /usr/bin. If you have a newer version of gcc installed, you may need to help Python's configure find /usr/bin/gcc by using the following:

export CC=/usr/bin/gcc
./configure
