I guess you need to link with libstdc++. Or compile with g++ instead of gcc, then libstdc++ will be linked by default.

Apparently your extension has been compiled with g++ and you didn't linked the stdc++ library. You need to add something like this in config.m4:

  PHP_SUBST(YOUREXT_SHARED_LIBADD)
  PHP_ADD_LIBRARY_WITH_PATH(stdc++, "", YOUREXT_SHARED_LIBADD)

See here for an exemple: http://svn.php.net/viewvc/pecl/rar/trunk/config.m4?revision=299933&view=markup
