Comment (by fbissey):
I did change the patch a little bit to allow for building against
uninstalled libcsage
{{{
+for m in cython_modules:
+ # Add csage as first library for all Cython extensions.
+ # The order is important, in particular for Cygwin.
+ m.libraries = ['csage'] + m.libraries
+ # For sage-on-gentoo we need to be able to compile against an
uninstalled libcsage
+ m.library_dirs= m.library_dirs + [os.path.join(SAGE_SRC, 'build',
'lib')]
}}}
But I got something strange at install time. And install_system_lib
doesn't respect "--root=" argument for setup.py which is also not good.
I am trying a vanilla build on OS X (yosemite) - with your original patch
- and it fails

I'll look at how libcsage.dylib was linked earlier but I suspect it was
given a wrong "type" (bundle instead of dylib).
