Thanks for your help Hassan.
Here's the mfmk.log showing what threw the compile error.
I'll try 2) run mysql_config manually to see what it says.
and experiment with the compile stream to see if i can get it going
Would it be appropriate to pass this problem onto the Rubygem team, and/or
Mysql/Oracle people?
Your suggestion to use MacPort will be my last resort
Thanks again
Dave
