Thank you very much for looking into this.

I have corresponding files in /usr/include for 2.7 but not for 3*:
alex at t61p:~/P3env/env$ ls -ld /usr/include/python*
drwxr-xr-x 2 root root 4096 Apr  8 19:05 /usr/include/python2.7

alex at t61p:~/P3env/env$ ls
bin  lib
Nothing in the env file (generated by virtualenv.)

My Ubuntu 14.04 system comes with Python3 by default so it does exist:
alex at t61p:~/P3env/env$ which python3
/usr/bin/python3
It's a mystery why it doesn't come with the corresponding include 
directory.

I'm guessing this is a system level problem that can probably only be 
solved by someone at Ubuntu or one of the lxml maintainers.

Thanks again,
Alex
