Actualy, reality turned differently. The patch was becoming rather 
invasive and therefore I backed up a little. The current firebrd2.5 
packages provide /usr/lib/libib_util.so in the libib-util package. 
That can be used both for linking against and at run-time.

Now the only question remains if this can be used on 2.1 and 2.0, 
similarly to libfbclient2. It exports only two functions -- 
ib_util_init and ib_util_malloc. I guess the semantics are the same, 
but am not sure of the internals.

I'll ask firebird-devel.
