[racket-dev] Racket installs more files on amd64 than on i386

I'm seeing a weird behavior of the installation of Racket 5.3.1 on 
OpenBSD (I don't know if other OS are affected or not).

On amd64 Racket installs this files:
/usr/local/share/racket/doc/images/pict_168.png
/usr/local/share/racket/doc/images/pict_169.png
/usr/local/share/racket/doc/images/pict_170.png
/usr/local/share/racket/doc/images/pict_171.png
/usr/local/share/racket/doc/images/pict_172.png
/usr/local/share/racket/doc/images/pict_173.png
/usr/local/share/racket/doc/images/pict_174.png

/usr/local/share/racket/doc/images/pict_177.png
/usr/local/share/racket/doc/images/pict_178.png
/usr/local/share/racket/doc/images/pict_179.png
/usr/local/share/racket/doc/images/pict_180.png
/usr/local/share/racket/doc/images/pict_181.png
/usr/local/share/racket/doc/images/pict_182.png
/usr/local/share/racket/doc/images/pict_183.png

On i386 Racket doesn't install these files. I use the same options for 
to compile both packages. Any idea?
