>Description:
As of the import of thunderbird-6.0 to pkgsrc-HEAD, mail/thunderbird
fails packaging as follows:

[...]
=> Automatic manual page handling
pkg_create: can't stat 
`/d0/build/pkgsrc/mail/thunderbird/work/.destdir/usr/pkg/include/thunderbird/NativeX64.h'
===> Building binary package for thunderbird-6.0
=> Creating binary package /d0/build/pkgsrc/packages/All/thunderbird-6.0.tgz
pkg_create: can't stat 
`/d0/build/pkgsrc/mail/thunderbird/work/.destdir/usr/pkg/include/thunderbird/NativeX64.h'
pkg_create: lstat failed for file include/thunderbird/NativeX64.h: No such file 
or directory
*** Error code 2

Stop.
make: stopped in /d0/nbsd/pkgsrc/mail/thunderbird
*** Error code 1

Stop.
make: stopped in /d0/nbsd/pkgsrc/mail/thunderbird

>How-To-Repeat:
On i386-5.99.55 system, with pkgsrc-2011Q2, update mail/thunderbird to
the HEAD revision of pkgsrc and attempt to "make package" or "make
install".

Also, in /etc/mk.conf, set:

PKG_OPTIONS.thunderbird+=mozilla-enigmail -mozilla-lightning
