debian packages for pycryptopp

[warner]

We need .deb packages of pycryptopp to make the tahoe .deb packages at all usable, now that HEAD requires pycryptopp. The process will be similar to the one I used for debianizing zfec.

I think this needs to be done before the 0.7.0 release, otherwise the 0.7.0 debs will be unusable.

done, for sid, etch, edgy, feisty, and gutsy. As usual we're skipping dapper, since it's too old to conveniently handle. I used the 'stdeb' plugin, by running 'py2dsc pycryptopp-0.2.6.tar.gz', which gave me a .orig.tar.gz, a .diff.gz, and a .dsc .

I then unpacked a source tree using those files and modified it as follows:

• setup.py: remove the declared dependency upon darcs_setuptools, since that would require yet another debian package, and it's only actually needed to create a source tarball
• setup.py: prefer /usr/include/crypto++ to /usr/include/cryptopp, since the recent debian change (to symlink /usr/include/cryptopp to crypto++) didn't also symlink the library files. The include/ symlink tricked our setup.py into thinking that it should look for /usr/lib/libcryptopp.a, which doesn't exist.
• debian/control: declare a build dependency upon libcrypto++-dev

On edgy, I also had to modify the debian/control build-dependency on debhelper to allow it to be slightly older.

The resulting source package is named 'pycryptopp', and the binary package is named 'python-pycryptopp'.
