Hi all,

I am having a bit of a hardtime installing the mysql gem on  
an AMD 64:  
Here are all the details I think that could be useful. The  
system is an RHEL 4(Update 3) with Ruby freshly installed  
from sources (so is rubygems). I (think I) have all the  
necessary rpms for building the native extensions, yet  
no luck at all. Any help is greatly appreciated, TIA.

Could not create Makefile due to some reason, probably lack of  
necessary libraries and/or headers. Check the mkmf.log file for more  
details. You may need configuration options.
