Ah, that does the trick.

I have updated the libungif, and libpng packages to fetch from the
fgs-dev/fgs-cache since fetches from sourceforge result in pulling
back some html and the build process breaks down.

I have also updated the proj package to use a newer datum shift
file package since the old one has moved, and is less complete.

To build libjpeg on my 64bit linux system I found I had to do some
hackery since the ancient libtool in jpeg6b does not recognise x86_64.
But I don't judge this to be suitable to commit.  I am pursuing getting
a libjpeg 6.1.0alpha release produced by the libjpeg team (of which
I am a not very helpful member) and when that occurs I'll update things
to point to it.

Assuming I can keep things working properly, may I update FGS to
more modern proj, gdal, and libgeotiff packages?

I'd also like to factor some gdal dependencies out into plugins.
For instance postgres, and libecw.  I'm also interested in preparing
gdal-python bindings support which seems practical since FGS already
includes python.

Any advice on building add-on packages like gdal-python or gdal-ecw?
I dont' quite understand why I need to use "gdal-base" as the name of
the gdal package when I do "fgsdev custom_build_list create" and I
wonder how that might relate to gdal plugin packages.

I guess I should try to use the mapserver python mapscript package
as a guide?

I'm not too frustrated, but clearly some work is needed to make FGS
more accessable to new developers.  For the time being I'm making a
few notes at:


Once I have some more experience contributing to FGS I hope I'll be
in a better position to talk about whether it would be suitable as
the "OSGeo Linux Distribution" and then trying to get others involved.
