rebuilding pkg_install fails

[Pierre Abbat <phma@xxxxxxxxxxxxx>]

I just updated pkgsrc and pkgin to 2011Q2, then upgraded an unimportant 
package (gforth). It warned about a newer pkg_install version but installed 
the package anyway. So I attempted to build a pkg_install package as 
described in http://www.dragonflybsd.org/docs/howtos/HowToPkgsrc/#index10h3 . 
I got the following:
