Debugging

Is there any way to debug a procedural language shared library when you can't createlang?

I get this...
L-897V601: {1} createlang pltcl template1
DEBUG: InitPostgres
DEBUG: StartTransactionCommand
DEBUG: PortalRun
DEBUG: CommitTransactionCommand
DEBUG: StartTransactionCommand
DEBUG: PortalRun
DEBUG: CommitTransactionCommand
DEBUG: StartTransactionCommand
DEBUG: ProcessUtility
createlang: language installation failed: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
L-897V601: {2}

and in the log...

DEBUG: 00000: ProcessUtility
LOCATION: PortalRunUtility, pquery.c:741
STATEMENT: CREATE FUNCTION "pltcl_call_handler" () RETURNS language_handler AS
'$libdir/pltcl' LANGUAGE C;
CREATE TRUSTED LANGUAGE "pltcl" HANDLER "pltcl_call_handler";

DEBUG: 00000: reaping dead processes

None of which is helping me any.

All its friends seem to be there...

L-897V601: {7} ldd pltcl.so
pltcl.so:
-ltcl84.1 => /usr/pkg/lib/libtcl84.so.1
-lpthread.0 => /usr/lib/libpthread.so.0
-lm.0 => /usr/lib/libm387.so.0
-lm.0 => /usr/lib/libm.so.0
-lc.12 => /usr/lib/libc.so.12

Any advice will be appreciated.
