Any idea why narray.h doesn't get found (or more to the point, why the 
narray header dir doesn't get put on the include path)?

This is via "gem install na_str-0.1.0.gem", with the gem downloaded from 
the above link:

Makefile:134: warning: overriding commands for target 
`/usr/local/lib/ruby/gems/1.8/gems/na_str-0.1.0/lib'
Makefile:132: warning: ignoring old commands for target 
`/usr/local/lib/ruby/gems/1.8/gems/na_str-0.1.0/lib'

/usr/local/lib/ruby/site_ruby/1.8/x86_64-linux   -c na_str.c
na_str.c:3:20: error: narray.h: No such file or directory
na_str.c:4:27: error: narray_config.h: No such file or directory


The extconf.rb assumes that narray is in sitearchdir, but
my narray is installed as a gem and its headers are at:

/usr/local/lib/ruby/gems/1.8/gems/narray-0.5.9.7/narray.h
/usr/local/lib/ruby/gems/1.8/gems/narray-0.5.9.7/src/narray.h

Does anyone know how to tell extconf to look for headers in the gem dirs?
