Alex,

Does this only fail after you've tried to load an octave-forge package?

I am currently able to build Octave with 64bits on MacOS 10.7 using MacPorts 
for dependencies (I haven't tried to build the 32 bit version there), and am 
able to build a 32bit version on 10.6 using Fink for dependencies. My Mac with 
Fink installed is currently being updated (the packages are a few months old 
now). I hope to confirm I'm able to build the developers sources and that I 
don't encounter the cs-list error later today.

I plan to compare Fink's info file to the build script I use for the developers 
sources on 10.6.

        http://pdb.finkproject.org/pdb/package.php/octave

At first glance I notice you've made a lot of changes in Fink's support of 
Octave.  I'll update the etc/README.MacOS file to reflect that.
