Are you sure that third party programmers correctly rewrote
windows FreeUDFLib to Linux? As I know, there is some kind of
subset of FreeUDFLib, ported to C and thus compilable on Linux.

But, original FreeUDFLib had some problems, at least with blobs,
and with allocating memory not with ib_util.
I rewrote windows version myself at 2003.

gbak does not check dlls or so files. It just backups and restores
metadata. Even if you deleted udf files, database will still pass
backup/restore. But any function call from the missing udf will result
error message like you see.
Also such error message can be caused by some non-existing files that
udf library want to use.

I know how to check this on Windows, but don't know how to do
this (check so dependencies) on Linux.
