Thank you very for your replies. I guess it we may use the `apt-build' facilities to rebuild our favorite scientific libraries: unfortunately the `apt-build' package conflicts with `pentium-builder'. Nevertheless, a quick look leads to think that they can be merged as they both use a wrapper. Is it a relevant idea ? Jerome
Ah, fair enough. Scientific libraries and crypto (OpenSSL apparently gets a HUGE speed boost one some sparc CPU when compiled with processor specific optimisations) are the expcetion to the rule. Generally, though, it doesn't gain you much :-)
