OK.

(Sorry, then it was probably 300 MB after the contents were already built.)

I could fetch cca. 160 files from their SVN, but I don't think this
would be practical.

I can extract those files, compress them (the compressed file would
only be 560K) and upload them somewhere, so that they would end up on
MacPorts mirrors. Or ask an admin to upload it if I recall a recent
discussion correctly? This would actually greatly simplify the process
(no need to specify which nontrivial subset of files to extract).

NB: Users who actually depend on wxPython would still need to fetch
those 30 MB, but that doesn't cover all wxWidgets users. An
alternative is to install those files by py-wxpython-2.8 which needs
to fetch wxPython anyway, so no extra downloads would be needed, but I
would probably need to rewrite fetch, checksum and extract phase from
scratch? I have no clue how to do that.
