undefined symbol: deflate

hi all,

I built ClearSilver 0.10.5 on Linux and found that neo_cgi wouldn't
load... producing this error message at runtime:

neo_cgi.so: undefined symbol: deflate

A number of other people on the Internet seemed to have run into this
also, but I could not find a definitive solution.

I noticed that the problem was caused by the ordering of the ld
command line.
The "-lz" option was occurring before the other -l options
containing the ClearSilver code.  This caused "deflate" to be left
undefined in the symbol table, instead of being loaded from libz.a.

I was able to get it working by patching python/setup.py to add a
second "-lz" at the end (see below).  This is not a general solution
since it assumes that compression is enabled.  Is there a better way
of dealing with link order issues in distutils?

thanks,

Jonathan Mark
