wish error - Mailing list pgsql-interfaces

Hello,

I have tried running pgaccess with the command line:

wish -f pgaccess.tcl

When I do this, I get the following error message:

Error in startup script: couldn't load file "libpgtcl.so":
/usr/lib/libpgtcl.so: undefined symbol: crypt
    while executing
"load libpgtcl.so"
    (procedure "main" line 3)
    invoked from within
"main $argc $argv"
    (file "pgaccess.tcl" line 4606)

I have recompiled postgreSQL 6.3 and moved libtcl.so to /usr/lib.
I am running RedHat 5.0. Can anyone suggest how I can get this
to work?

Thanks.

Kenji
