When trying to configure babel 3.6-4 it claims that manfnt.mf is missing in the "Rebuilding 'amstex' format" section and after the "Appending font creation commands to missfont.log" message it places utselfe in some sort of loop which I stoped when /usr/lib/texmf/amslex.log had grown to about 720 Mb, and started generating "Filesystem is full" errors.
