We must adjust 'inc_dirs' and 'lib_dirs' in setup.py.

Well, this is funny. When running "python -c "import zlib", /usr/bin/python is
called:
execve("/home/cyril/.guix-profile/bin/python", ["python", "-c", "import zlib"],
[/* 23 vars */]) = 0
I had to use an absolute path to run the right interpreter:
execve("/home/cyril/.guix-profile/bin/python",
["/home/cyril/.guix-profile/bin/py"..., "-c", "import zlib"], [/* 23 vars */])
= 0
and it fails to load zlib.
Anyway, I think the zlib module was not found because setup.py only looks for
the libraries/headers in a few hardcoded directories
lib_dirs = self.compiler.library_dirs + [
'/lib64', '/usr/lib64',
'/lib', '/usr/lib',
]
inc_dirs = self.compiler.include_dirs + ['/usr/include']
Could you confirm that:
1) This patch fixes your zlib issues
2) A similar error occurs when importing other modules, such as bz2
?
I do not think there is a more elegant solution than patching setup.py. I tried
running "CFLAGS=-I/path/to/zlib/include ./configure" and
"CFLAGS=-I/path/to/zlib/include make" but it does not seem to make any
difference.
