==========


greetings,

environment:
running 10.04
mysql version: mysql ver 14.14 distrib 5.1.41, debian-linux-gnu (i486) using readline 6.1
ruby: ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]

trying install ruby gem 'mysql'.
reading, should able a:
$gem install mysql

way, using sudo or not has same result.

disappointing because have done lot of work learn mysql discover can not use ruby (at least gem).

routinely use $mysql "guess" mysqlclient working.

appreciated.
steve.

not create makefile due reason, lack of
necessary libraries and/or headers. check mkmf.log file more
details. may need configuration options.

i believe need install header files resolve issue
