[PyMOL] Cannot compile svn source

Dear all,

I am trying to compile pymol from source following the instructions 
here: http://www.pymolwiki.org/index.php/Linux_Install

It used to work for me a while ago but now the compilation hangs without 
error. Pressing return give me back the terminal prompt. The compiling 
process does not stop always at the same point.

I am using Linux Mint 17 64 bits (based on Ubuntu).

Anyone has seen such behaviour?

Cheers,
Arnaud
PS: see below example of output
