gtk-2.10.9 doesn't compile

[Vittorio]

Dear All,

Under a fresh installation of 6.2 I recently updated via 
portsnap the ports tree and recompiled what was needed (including 
portupgrade!), BUT after issuing as root:

portupgrade gtk
I obtain the 
following obscure, esoteric diagnostic:
<snip>
gmake[2]: Leaving 
directory `/usr/ports/x11-toolkits/gtk20/work/gtk+-2.10.9/gdk'
gmake
[1]: *** [all-recursive] Error 1
gmake[1]: Leaving directory 
`/usr/ports/x11-toolkits/gtk20/work/gtk+-2.10.9'
gmake: *** [all] Error 
2
*** Error code 2

Stop in /usr/ports/x11-toolkits/gtk20.
** Command 
failed [exit code 1]: /usr/bin/script -qa /tmp/portupgrade.55166.1 env 
UPGRADE_TOOL=portupgrade UPGRADE_PORT=gtk-2.10.7 UPGRADE_PORT_VER=2.
10.7 make
** Fix the problem and try again.
</snip>

What shall I do?
