checkout of jython, which uses a indirection for part of the checkout
to svn.python.org no longer functions correctly.  To address this
the following has been done:
1) The svn checkout task now has a parameter to ignore failure---this is
   not ideal but the checkout of jython will checkout all and timeout
   on the indirection then finally fail.
2) The CPythonLib, which is constructed from python.org source is now
   take from a download of a the 2.5.4 python source package.
3) MD5 checksums have been updated to reflect the changes.
4) Oddly the jython build will fail with three of the source files containing
   a non-ASCII character in the some comments.  While these files comply with
   the python standard by indicating the character encoding to use, they still
   do not build under ubuntu 8.10, but do build under ubuntu 9.04.  A patch
   has been added to jython.patch to change the characters to an approximate
   ASCII equivalent.
