Mac OS X, PostgreSQL, PL/Tcl

Hoping someone can help me figure out why I can't get PL/Tcl to load
without crashing the backend on Mac OS 10.3.2.

I compile Tcl, PostgreSQL, create the database and then run the
following:

create function plpgsql_call_handler() RETURNS LANGUAGE_HANDLER
as 'plpgsql.so' language 'c';

create trusted procedural language 'plpgsql'
HANDLER plpgsql_call_handler
LANCOMPILER 'PL/pgSQL';

create function pltcl_call_handler() RETURNS LANGUAGE_HANDLER
as 'pltcl.so' language 'c';

create trusted procedural language 'pltcl'
HANDLER pltcl_call_handler
LANCOMPILER 'PL/Tcl';

The PL/pgSQL part loads fine. The PL/Tcl part crashes the server, and
psql reports this:

psql:/Users/scott/pgtest/add_languages.sql:12: server closed the
connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
psql:/Users/scott/pgtest/add_languages.sql:12: connection to server was
lost

I have tried the exact same procedure on Linux without any problems
using the exact same scripts, setup etc. I've tried both PG 7.4.1 and a
CVS copy from 11 Feb. I've used gcc 3.3, 3.1 and 2.85. I've tried
loading PL/Tcl without loading PL/pgSQL at all, same problem. I tried
Tcl 8.4.3, 8.4.4 and 8.4.5. pgtclsh runs fine.

I used ktrace to attach to the PG process and it's generating a
SIGSEGV. I get several "file name too long" errors before the SEGV.
Problem is probably not with PG, but could be with Tcl and/or Mac OS X
loadable libs. Here's the significant portion of it (you can find the
whole output trace at http://scottg.net/pgktrace.txt)
