I added a note on that bug, which is for python 3.2, and marked as fixed released via a setup.py patch, but the build I do is as the README says, ./configure, make. > Try again. It is working for me and has a patch. I have tried building http://www.python.org/ftp/python/2.6.4/Python-2.6.4.tar.bz2 (i.e. not the Ubuntu version, but the upstream version) on Ubuntu 11.04 beta 2 amd64. It failed with the same: Failed to find the necessary bits to build these modules: _bsddb _hashlib _sqlite3 _ssl _tkinter bsddb185 dbm dl gdbm imageop sunaudiodev zlib To find the necessary bits, look in setup.py in detect_modules() for the module's name. Failed to build these modules: crypt nis I built with ./configure, make, as in the README, not with python setup.py build, and that patch is for setup.py so does not make any difference. python setup.py build fails with numerous missing items, and include python2.7.1+ (the default python version on Ubuntu) statements. There is also a packaged version of python2.6.6 in this release, so I assume the Ubuntu patched version builds. The upstream version same problem. The latest Python 2.x is 2.7.1. Also the Ubuntu patched version must build. The upstream does not. So apt-get source python2.6 gets the ubuntu source for 2.6.6, and produces the file python2.6_2.6.6-6ubuntu7.diff.gz [260K] which I can't post now as my server room air conditioning failed 4 times in an hour and I'm shutting down now, probably until some time Monday. It does mention crypt. 0 jan@muizenberg:/var/autofs/misc/home/jan$zgrep crypt python2.6_2.6.6-6ubuntu7.diff.gz +<LI><A HREF="#4.81">4.81.
