Be careful about the Linux directories: For example on Gentoo
Linux, since FB 2.0.3, it's not /opt/firebird/UDF any more,
but /usr/lib/firebird/UDF.

And since 2.0.3.12981.0-r6, I must write
RootDirectory = /usr/lib/firebird
UdfAccess = Restrict UDF
into /etc/firebird/firebird.conf - else FB searches its UDFs
somewhere in /usr/bin/UDF or something like that, I guess.

But "broken pipe" seems to be another error - I got SQL error
-104 (FB error 335544343, "invalid_blr") while FB couldn't
find its UDFs...
