-------------------------+--------------------------------------------------
using sage 3.2.3, I'm trying to build a new module with a .pxd file
containing this line
{{{
#include "gmp.h"
}}}
note that the line is commented. The build fails with the following
traceback
{{{
sage -b

sage: Building and installing modified Sage library files.
Installing c_lib
scons: `install' is up to date.
Updating Cython code....
Traceback (most recent call last):

filename)
IOError: could not find dependency gmp.h included in

}}}
There is probably a problem with the regexp on line 228 of
[http://www.sagemath.org/hg/sage-main/file/b0aa7ef45b3c/setup.py
setup.py]. One can reprouce the bug with this snipet
{{{
dep_regex = re.compile(r'^ *(?:cimport +(\S+))|(?:from +(\S+)
*cimport)|(?:include *[\'"]([^\'"]+)[\'"])', re.M)
m.groups()for m in dep_regex.finditer('#include "gmp.h"'):
m.groups()
}}}
which results in
{{{
(None, None, 'gmp.h')
}}}
