I have installed the Firebird MacOS X 1.5.1 classic server on my
powerpc (iMac), however it does not run properly.

I test a client connection to the database server (via squirrel), and
see the fb_inet_server process displayed when running the "top"
command. Then it disappears after a couple of seconds and returns a
connection error to the client.

I try to run "isql" manually and get several errors indicating some
missing symbols, like:
./isql undefined reference to _btowc expected to be defined in
/usr/lib/libSystem.B.dylib
./isql undefined reference to _iswctype expected to be defined in
/usr/lib/libSystem.B.dylib
./isql undefined reference to _btowlower expected to be defined in
/usr/lib/libSystem.B.dylib
./isql undefined reference to _btowupper expected to be defined in
/usr/lib/libSystem.B.dylib
etc...

Am I correct in my findings that the current Firebird MacOSX installer
will only work for OSX 10.3 and higher?
