When I try to install Perl 5.12.2 with perlbrew, I get an error at the end because the CPANPLUS tests fail.

### Since not all tests were successful, you may want to run some of
### them individually and examine any diagnostic messages they produce.
### See the INSTALL document's section on "make test".
### You have a good chance to get more information by running
### ./perl harness
### in the 't' directory since most (>=80%) of the tests succeeded.
### You may have to set your dynamic library search path,
### LD_LIBRARY_PATH, to point to the build directory:
### setenv LD_LIBRARY_PATH `pwd`; cd t; ./perl harness
### LD_LIBRARY_PATH=`pwd`; export LD_LIBRARY_PATH; cd t; ./perl harness
### export LD_LIBRARY_PATH=`pwd`; cd t; ./perl harness
### for csh-style shells, like tcsh; or for traditional/modern
### Bourne-style shells, like bash, ksh, and zsh, respectively.

You're not going to find this comforting but I had no hitches installing perl 5.12.2 under Perlbrew just a couple of weeks ago :(
The differences maybe:
I'm still using old version of Perlbrew (0.03).
I installed Perlbrew direct and not via CPAN by using these steps (sorry if repeating advice from before):
curl -LO https://raw.githubusercontent.com/gugod/App-perlbrew/master/perlbrew
chmod +x perlbrew
./perlbrew install
Something changed on CPANPLUS in last couple of weeks (I can't see anything though)
CPANPLUS has some old bugs which may under certain conditions not play well with perlbrew or perhaps your environment?: https://rt.cpan.org/Public/Dist/Display.html?Name=CPANPLUS.
So may not be a Perlbrew issue at all. You may find you hit same test failure if you try and compile Perl 5.12.2 directly. To compile locally please consult general and any specific README file in the source tar ball. The general steps once tar ball is unpacked are:
sh Configure -Dprefix=/home/your_username/your_local_dir_for_perl-5.12.2
make
make test
make install
Anyhow, CPANPLUS is another CPAN shell and isn't essential. So if thats the only tests failing on the install then you could ignore them and force an install. Which going back to perlbrew is:
perlbrew install perl-5.12.2 -f
