Please describe the problem:

I started receiving a message that gtkdoc-rebase is not found when building 2.12.3 on Solaris 9, which kills the build process. Upon further investigation it looks like the test for gtkdoc-rebase can never be false:

A quick grep -R for gtkdoc-rebase show this through out the Makefiles in trunk:

       if test "`which gtkdoc-rebase`" != ""; then \
        gtkdoc-rebase --relative --dest-dir=$(DESTDIR) --html-dir=$(DESTDIR)$(TARGET_DIR) ; \
          fi

This can never be true because which always returns "no $ found...." when the command is not within $PATH. So the script believes gtkdoc-rebase exists and then fails.

This is probably also related to this bug:

Does this happen every time?
