broken firefox port?

[Stefan Miklosovic]

hi,

while upgrading firefox 3.0.11-1, this error appeared to me:

--->  Upgrading 'firefox-3.0.11,1' to 'firefox-3.0.13,1' (www/firefox3)
--->  Building '/usr/ports/www/firefox3'
===>  Cleaning for firefox-3.0.13,1
** Command failed [exit code 1]: /usr/bin/script -qa

UPGRADE_PORT=firefox-3.0.11,1 UPGRADE_PORT_VER=3.0.11,1 make
** Fix the problem and try again.
** Listing the failed packages (-:ignored / *:skipped / !:failed)
        ! www/firefox3 (firefox-3.0.11,1)       (unknown build error)

any ideas ?

I updated my port tree by cvsup
