This strongly suggests that the collection metadata file (stored in
GNU DB format) is not readable by the gdbm libraries on the 2nd machine.
In other words, the two computers use incompatible gdbm file formats.

The more common reason for this is if the machines are of different
"endians" - for example windows on intel vs osx on powerpc. I've also
seen it with different operating systems on the same architecture - eg
windows on intel and freebsd on intel.

You can either copy the archives/ directory of the collection over and
re-build on the unix machine, or use the "db2txt" program that comes with
greenstone to export the collection metadata into a text file, copy that
over, and use "txt2db" on the unix machine to manually re-create the
gdbm file.

I think these is discussed in the online greenstone FAQ. If not, they'll
need to be updated in the new year :)
