my first instinct would be to replace that elegantly written piece of 
code with something that is supported by community and still under 
development, for example GSL.

Second idea would be to replace N3 with N4 ( 
http://www.slicer.org/slicerWiki/index.php/Documentation/4.0/Modules/N4ITKBiasFieldCorrection 
) and just write a wrapper scripts like nu_correct and nu_evaluate that 
would mimic behavior of N3 using calls to N4 and ITK.
