By "it" do you mean Decimal, or Python 2.4 alpha 2?  I think gmpy should
build happily with the latter, and interoperate sensibly with Decimal
anyway -- as gmpy's author I'd be quite happy to fix gmpy if it's broken
in either respect.

2.4 is not currently recommended for production work (that's why it's in
Alpha -- very good for an alpha, but it's still not a final release).
But such support modules as gmpy need to get moving to support 2.4 in
order to be ready for it well before final release...
