compile error with Ruby

hi, just a quick heads up. noted the following issue with freeradius 2.1.6 when compiling. no Ruby installed - configure script WARNs and doesnt try including Ruby support only Ruby tools installed - configure thinks all is okay - make then fails because ruby.h is not present Ruby development package installed - configure says all is okay and make works (ie ruby-devel must be installed (as expected!) but if the system has only the Ruby binary installed then configure stage thinks its okay to build in Ruby support. not a show stopper because development has to be flagged on the congigure line (?) but a little quirky - i cant recall any other modules that think its all okay if just the runtime binary is present (eg openssl) alan
