Hi,

Faced some compilation issues: any hints?

x86_64-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -g -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -fPIC -I/usr/include/libxml2 -I/var/www/piati/pyenv/build/lxml/src/lxml/includes -I/usr/include/python3.3m -I/var/www/piati/pyenv/include/python3.3m -c src/lxml/lxml.etree.c -o build/temp.linux-x86_64-3.3/src/lxml/lxml.etree.o

src/lxml/lxml.etree.c:8:22: fatal error: pyconfig.h: No such file or directory

#include "pyconfig.h"

                  ^

compilation terminated.
