I'm finding this build failure confusing. Hopefully somebody can shed some light.

tdebindings builds without failure on Slackware 13.1 and 13.37, but fails on Slackware Current (soon to be Slackware 14). The problem is not gcc 4.7.1 related because this failure started before Current updated to 4.7.1 (only yesterday). I previously built tdebindings on Current a few weeks ago. What changed between then and now? Ruby was updated from 1.9.1 to 1.9.3 and that is the only related change I notice.

That is what the failure message indicates too.

In tdebindings/qtruby/rubylib/qtruby/Qt.cpp:

#include <ruby.h>

In ruby-1.9.1, ruby.h:

#include "ruby/config.h"

In ruby-1.9.3, ruby.h:

#include "ruby/config.h"

For both, config.h is installed at:

/usr/include/ruby-1.9.1/i486-linux/ruby/config.h

I don't know why ruby 1.9.3 uses ruby-1.9.1 as a parent directory rather than ruby-1.9.3. Could that be the problem?

How do I work-around this failure?
