I'd strongly recommend you to upgrade to the latest pynifti version.

Since you are building from source, please get the latest snapshot of the 0.4 series maintenance branch: http://git.debian.org/?p=pkg-exppsy/pymvpa.git;a=snapshot;h=5b3d186656c6a6f90a931f51badeb266460be0e1;sf=tgz That one will spare you same hassles. Maybe that already helps. Please come back if it needs more improvements.
