[rescue] messaging server 5.2 starting error on solaris10 zone.

[giant]

i installed the messaging server 5.2 on my solaris10(sparc) zone .
but when i start the server,get the follow error:

-bash-3.00# ./start-msg 
/var/sun/ims52: Starting STORE daemon .... done: 14296
/var/sun/ims52: Starting POP3 daemon .... done: 14309
/var/sun/ims52: Starting IMAP4 daemon .... done: 14323

ld.so.1: /var/sun/ims52/bin/msg/imta/bin/imtacli: fatal: libimta.so: open

i have never met the error on solaris8/9, how can i correct it?
