I don't have the facility to build x86_64 RPMs so I am happy to take the
ones you build and host them on my site.  The fix for adding back the
-fPIC flag needs to be finer grained than commenting out the entire
patch - Fedora won't accept packages compiling with -O3, you have to
honour RPM_OPT_FLAGS for compilation unless you can come up with a very
good reason.  What I propose is a modifying the patch to preserve -fPIC
only, but not -O3?

I need to investigate some more into the Python thing.  My Fedora
reviewer told me to use sitearch because Mapnik was installing
architecture specific files under Python.  I am not entirely convinced
by this - perhaps Artem could help here.  The comment in question is at
the end of:

Thanks for the fix.  The inclusion of the fonts on Mapnik was
highlighted as a problem in the review for inclusion in Fedora, so I
snipped them out of the Scons install.

I would hope to get most of the SPEC files (Mapnik, TileCache,
OpenLayers) upstream, either in Fedora or in the source tarballs for the
applications.  It is probably worth adding the osm2pgsql.spec file to
the osm2pgsql directory in the OSM SVN.  The SPEC files, patches,a nd
scripts, are currently maintained in my SVN:

	http://www.passback.org.uk/svn/fedora/rpms/

Not sure what the best thing to do the with osm-base and osm-slippymap
packages is.  The spec files are at the above URL, and the source is
kept in subversion:

Comments and feedback welcome,

Keith.
