M:B declares an unversioned dependency on ExtUtils::Install. There is a bug in EU:I 0.29 that causes a M:B fakeinstall to be insufficiently fake: it actually creates the libdir and the directory to contain the packlist. This shows up in the M:B test suite, if one is testing as an unprivileged user, as one failed test in t/compat.t.
The dependency should be versioned, to require a version of EU:I that lacks the bug. Version 1.32 suffices. I don't know about versions between 1.29 and 1.32. -zefram
