The python version is 2.4.3,
As noted in the MEME installation guide the MEME tools require a version of Python between 2.6 and 2.7. It may be that your system has multiple versions of Python available. By default the MEME installation will simply use the first one found in the execution path. You can specify which version of Python MEME should used with the '--with-python' option of configure. For example
./configure --prefix=/home/meme --with-python=/usr/local/python2.6.1/bin/python
After re-running 'configure' you'll need to re-run
make clean
make install
