Thanks for the clarification. This is definitely not an open source in the sense of OSI. I would call this "publically available source" with a non-commercial license. It would be less confusing to readers like me if you reworded your webpage, replacing "open source" by something else. (You might also request that Berkeley allow you to release your program under GPL2+ :-)
In any case, it will be illegal to statically link your program to Sage and redistribute that package, as your license is not GPL-compatible. The best bet is to create an optional package, as Michael suggested. This process might be streamlined if you can strip off the gui front-end, as Carl suggested, so you have a command line interface to pipe inut and output back-and-forth using files or pexpect. IMHO, a numerical pde solver wuld be a very useful addition to Sage, even if only as an optional package.
