Ah, these FreeUDFLib declarations are a bit suspect. Try dropping the
function (DROP EXTERNAL FUNCTION 'f_WeekOfYear'), commit it, then declare
and commit it again minus ".dll". AFAIR, the server otherwise is looking
for 'FreeUDF.dll.dll', as it appends the platform-specific suffix at run-time.

Could also be that you don't have the UDF library configuration correct in
your configuration file. Can't help with that unless you tell us what
version of the server you are using.
