How to make check when building gcc46

[Takeshi Kobayakawa]

Does someone know how to 'make check' in gcc46 package of macports?
'port test' seems not working.

I would like to contribute to gcc's C++ standard library (libstdc++), in
order to handle std::locale correctly on darwin for other than "C" or
"POSIX" locales. I suppose I implemented a bunch of code that seems
working correctly, and have to check the code now.

Although I installed dejagnu, tcl and expect packages which are
required to execute the make check target, I still get some errors:
ERROR: (DejaGnu) proc "get_shlib_extension" does not exist.

The relevant part of messages are:
		=== libstdc++ tests ===
