Problem building mysql gem

[Michael Satterwhite]

I've just switched to Fedora and am trying to do a "gem install mysql".
Right at the beginning, I'm getting the error
------------------
find_library: checking for mysql_query() in -lmysqlclient...
-------------------
- no

"gcc -o conftest -I. -I/usr/lib/ruby/1.8/i686-linux -I.

crypt -lm -lc"
conftest.c: In function ‘t’:
conftest.c:3: error: ‘mysql_query’ undeclared (first use in this
function)
