The problem is that t/tools/mk_language_shell.t attempts to use an installed parrot instead of the one being currently built.  This can obviously fail if the installed parrot isn't a good match for the one being built.

Generally, I think it's a bad idea to assume that a random parrot executable that happens to be in the installation directory is compatible with the current parrot being built.

I'd propose a patch, but the code in question was explicitly added in TT #1890, so reverting that fix might be simpler, but will still leave the deeper problem of setting up an appropriate environment for the test.  I haven't invested the time necessary to study the issue in detail, but I think that relying on a previously-installed parrot is probably not the most robust approach."	bug	closed	normal		testing	3.0.0	medium	fixed
