In terms of SGI marketing it did, I guess. :-) But the superscalarity
of the R5000 doesn't seem to be of much use with the standard ssh
The R5000-180SC is supposedly the fastest Indy, but there was also
a R4000-250 version. I guess it depends on the programs you run.

Use the package build infrastructure instead, like calling
linux32 dpkg-buildpackage -us -uc -rfakeroot 2>&1 | tee ../makelog
in the directory apt-get source created.
