Ah, you obviously did not read the INSTALL document.

The latest development version from git is a *development* version, not
a release, and Configure needs to be told

      $ ./Configure -Dusedevel -des

>     sh Configure -ds -e

Why use configure.gnu? Why?

-Dusedevel is not to sidestep the issue. If you want to work with a
development version, which is by no means meant to be installed as
production code, we expect you to explicitly tell Configure to allow
building a development perl

Now, again, where does 

  $ ./Configure -Dusedevel -des

perl - the development version - is build on many different
architectures (i596, x86_64, ia64, pa-risc, power4, …),
operating systems (OSX, Linux, AIX, HP-UX, OpenVMS, Windows, …),
C-compilers (GNU gcc, GNU g++, HP C-ANSI-C, xlc, clang, …) and in
various configuration combinations (-Duselongdouble, -Duse64bitall,
-Dusethreads, …) ON A DAILY BASIS, so I am pretty convinced that -
unless you are failing some build tools - your Linux system would
qualify to do a clean build out of the box (after you have read

Huh? That is unlikely to happen. The files in UU are temporary and only
used during Configure. They are generated by Configure to be used only
by Configure.
