Re: [DebToo-Devel] Some benchmarks from using apt-fu + modified pentium-builder

[Heitzso <heitzso@growthmodels.com>]

Problem is current libssl package doesn't build in sparc32
environment.  There's a bug in the package build setup.

BTW, lsh was recommended and it works wonders.  Slightly
less than 2 seconds to setup ssh/cvs-over-ssh, which is
remarkably better than the 10 or so seconds for setting
up ssh via openssl.  My email TSL still routes via openssl/libssl
and takes the 10 seconds, but otherwise ...
