I suppose the tricky point here may be technical, rather than legal.  
Essentially, the OD library gets linked into the Perl code, which is GPL, so 
it seems that anything between them (which the interface file, helper 
functions, and resulting wrapper code would be) would need to be 
GPL-compatible.  This makes it sound like LGPL would be the way to go, but it 
is really meant to allow commercial code to link into open-source libraries.

I will look at other licenses.  This is going to get tricky.

Really, this is somewhat beside the point.  I am confident that we can find a 
workable solution for the license, but I am still trying to find some 
interest in the module from developers, or there is not really any incentive 
to open-source it.
