pkgsrc bootstraps on HP WEBOS!

[John Maier <jmaier%happymolars.com@localhost>]

I've managed to bootstrap pkgsrc on HP Touchpad WebOS, an ARM7 Linux 
(busybox) derivative.  Everything looks great, and only minor system 
changes.
I then moved to attempt building a package, and the first dependency 
pkgsrc needed to resolve was digest.
The entire digest build goes great, but the installation doesn't go so well:

/mnt/webos/pkgsrc/packages/All/digest-20111104.tgz
pkg_create: lstat failed for file /media/internal/pkg/man/man1/digest.1: 
No such file or directory

One fine point, I'm building off NFS mount /mnt/webos/pkgsrc, and 
/media/internal/pkg is a mount on a NFS share.  The TouchPad's /usr and 
/opt storage is rather small, and the flash storage doesn't allow 
symbolic links.  I wouldn't expect NFS to be an issue, but it is worth 
mentioning.

Also, I noticed that all pkg builds are creating binary packages.  When 
did this become default behavior?

Thanks for any ideas why the install is failing.
