[pypy-dev] Building lxml

[nitralime]

Hello!

I'v tried to build lxml 2.3.2 with pypy 1.7 (linux64)
and got the following error:

------------------------------------------------------------------------------------
$ pypy setup.py build_ext -i

Next I have tried the following (which is probabely a "nonsense"):

Has anyone ever tried to build lxml with pypy?
What is the correct way to build an extension module?

Any feedback is very much appreciated!

Regards
Nik

PS: By the way, what do
pypy: /usr/lib/libssl.so.0.9.8: no version information available 
(required by pypy)
pypy: /usr/lib/libcrypto.so.0.9.8: no version information available 
(required by pypy)
mean? Both libraries are available on my PC.
