It is impossible to compile ruby vers. 1.9. on one of my LAMP servers with the latest Gentoo.
Here how it looks like:

configure:
 ruby-1.9.3-p194 # ./configure
 ...
 .ext/include/x86_64-linux/ruby/config.h updated
 ruby library version = 1.9.1
 configure: creating ./config.status
 config.status: creating Makefile
 config.status: creating ruby-1.9.pc

make:
 ruby-1.9.3-p194 # make

 XCFLAGS = -include ruby/config.h -include ruby/missing.h -fvisibility=hidden -DRUBY_EXPORT
 CPPFLAGS =   -I. -I.ext/include/x86_64-linux -I./include -I.
