[tex-live] Bug in install-tl-unx.tar.gz's contents

[tljack at forallx.net]

There is a bug in the install-tl-unx.tar.gz.

I unpacked it, cd'd to the directory "install-tl-20130426", then did ./install-tl.

I immediately get:

Loading ./tlpkg/texlive.tlpdb
./install-tl: open(./tlpkg/texlive.tlpdb) failed: No such file or directory at tlpkg/TeXLive/TLPDB.pm line 359.
