[pca] problems with 137137 kernel patch

[ghenry]

hello,
the machine is a Sun V440, S10U5. I'm trying to install kernel patch, 
and as you can see it failed:
# /etc/scripts/pca -i 137137-09
Using /var/tmp/patchdiag.xref from Feb/23/09
Host: calypso (SunOS 5.10/Generic_137111-05/sparc/sun4u)

It seems there is a problem with dependancies, as you can see after, 
when i look at the ssh patch:
calypso-root% /etc/scripts/pca -l 140774
Using /var/tmp/patchdiag.xref from Feb/23/09
Host: calypso (SunOS 5.10/Generic_137111-05/sparc/sun4u)
List: 140774 (4/267)

Patch  IR   CR RSB Age Synopsis
------ -- - -- --- --- 
-------------------------------------------------------
125555 -- < 02 R--  69 SunOS 5.10: patch behavior patch
138866 -- < 02 R--  91 SunOS 5.10: sharetab patch
137137 -- < 09 RS- 106 SunOS 5.10: kernel patch
140774 -- < 02 RS-   1 SunOS 5.10: sshd patch


Above, we see that kernel patch has two dependancies, but "pca -i 
137137" doesn't find it.

Am i wrong?

thanks in advance,
