portupgrade misbehavior

[Adam McLaurin]

Just had a very weird happening with portupgrade .. I can't explain it's
behavior:

-# pkg_version -v |grep "needs"
ImageMagick-5.5.7.16_1  <   needs updating (port has 6.0.1.3) 
apache-1.3.29_5         <   needs updating (port has 1.3.31)
kdebase-3.2.2           <   needs updating (port has 3.2.2_1) 
mod_php4-4.3.6,1        <   needs updating (port has 4.3.6_1,1) 
mozilla-1.7.r1,2        <   needs updating (port has 1.7.r2,2) 
p5-sdl-1.20.3_2         <   needs updating (port has 1.20.3_3) 
rhythmbox-0.8.3         <   needs updating (port has 0.8.4) 
sdl_gfx-2.0.10_2        <  needs updating (port has 2.0.11)

Why the h*ll did portupgrade try to recompile zsh? I can't think of any
logical explanation for this behavior. Perhaps I am missing something
simple here; or perhaps I stumbled across a bug in portupgrade (or even
ruby) ?

Thanks.
