Radius compiling problem....

I'm compiling gnu-radius to use with mysql.  i did the following....

./configure --with-mysql --with-lib-path=/usr/local/mysql/lib/mysql/ 
--with-include-path=/usr/local/mysql/include/mysql/

this worked fine.  then i did 'make' and was presented with an error 
about not being able to find mysql.h.  I found this reference in 
sql/mysql.c.  Line 43 was including mysql.h from the wrong path.  I 
changed it and 'make' went fine.  Is there something I did wrong or a bug?
