Comment (by uri@…):

 Yes!

 I checked my .bashrc, and found

 {{{
 export BZIP2=/opt/local/bin/bzip2
 }}}

 in it (I don't remember what application needed that definition).

 Then, after unsetting it:

 {{{
 $ unset BZIP2
 $ bzip2 Astro.txt
 $ bunzip2 Astro.txt.bz2
 $
 }}}

 So when env variable BZIP2 is not set, it works just fine. But why would
 that env var screw things up so badly? Isn't that a bug? What do you
 think?
