Yes, and moreover, there is a list of differences between the two here:
http://www.stsci.edu/resources/software_hardware/numarray/userguide

It seems like the differences should not affect Gnuplot.py,
but this is a question for Michael perhaps.

Howabout a condicional import in the relevant modules? (funcutils, etc)
Something like:

####
try:
    import Numarray as numeric_lib
except:
    import Numeric as numeric_lib
####

And then all internal references are made to "numeric_lib",
for instance 

return numeric_lib.asarray(m, Numeric.Float32)

I think it is fare to assume that the user will prefer Numarray
if installed, and I also think that Numeric will be around
for a loooong time. Sounds reasonable ?

pyfits and PyRAF use numarray instead of Numeric, so I have used  
Gnuplot.py with numarray.array inputs for more than half a year. 
Everything seems to work fine. I think numarray tries to be 
backward compatible with Numeric.
