Issue #7897 has been updated by vo.x (Vit Ondruch).


I guess this regression was introduced in r37016 by dropping this line [1] in mkmf. Not sure what was the intention, since creating directory seems unrelated to the timestamp dependencies IMO

Bug #7897: rubygems 2.0 has an incompatibility about installation of extension libraries if gem package does not contain lib directory

Hi,

rubygems 2.0 has an incompatibility about installation of extension libraries.

If a gem package does not contain lib directory,
an extension library file is copied as a file named "lib".

You can reproduce this problem by installing msgpack version 0.4.7.
