pgaccess problem on Solaris OS.

Dear everybody

My name is Koujiro iuchi,
I'd like to suggest me for my problem.

I was installed Postgresql-7.0 and some GUN Dev.tools into Solaris 8.
And so all of confugration and compile no error complete.

And then type "pgaccess",
Message indicate couldn't load file "libpgtcl.so":

of course tk8.3 and tcl8.3 configure with "--enable-shared" option
from unix source directory.

Detail ,

fabric% pgaccess
Error in startup script: couldn't load file "libpgtcl.so": ld.so.1:
/usr/local/b
in/wish: ??????¨??: libucb.so.1: open ???????????: ???????????£??

while executing
"load libpgtcl[info sharedlibextension]"
(procedure "main" line 3)
invoked from within
"main $argc $argv"
(file "/usr/local/pgsql/pgaccess/main.tcl" line 249)
fabric%

My envoronment:
Pentium III machine
Solaris 8 for Intel.
gun TK and TCL 8.3
Postgresql-7.0 source

Please advice me your experience.
Thank you
