Install Cpanm module error : No such file or directory opening compressed index

I got this error while installing Rest client perl module
$ HOME=/tmp /home/perl/5.10/bin/cpanm REST::Client
! Finding REST::Client on cpanmetadb failed.
! cannot open file '/tmp/.cpanm/sources/http%www.cpan.org/02packages.details.txt.gz': No such file or directory opening compressed index
! Couldn't find module or a distribution REST::Client


The problem is because of "LWP::Protocol::https" module. Removing the directory worked for me.
$ cd /perl_installed_path/perl/5.10/lib/site_perl/5.10.1
$ rm –rf LWP*
or try with option "--no-lwp"
cpanm REST::Client --no-lwp

This link helped me to find what i was missing: https://rt.perl.org/Public/Bug/Display.html?id=55980 and finally this worked for me

Step 1: find your lib path which has all libm* files

In most systems it will be under /usr/lib64. Search for the files in your system.
system:/usr/lib64 $ ls libm*
libm.a libmcheck.a libmenuw.so.5 libmpc.so.3.0.0 libmpfr.so.4 libmpx.so.0.0.0 libm.so libmvec.a libmagic.so.1 libmenu.so.5 libmenuw.so.5.9 libmpdec.so.2 libmpfr.so.4.1.4 libmpxwrappers.so.0 libmspack.so.0 libmvec_nonshared.a libmagic.so.1.0.0 libmenu.so.5.9 libmpc.so.3 libmpdec.so.2.4.2 libmpx.so.0 libmpxwrappers.so.0.0.0 libmspack.so.0.1.0 libmvec.so

Step 2: Use the path with glibpth option while doing configure

./Configure -des -Dglibpth='/lib/lib64 /usr/lib64'
or I see some forums suggested plibpth
./Configure -des -Dplibpth='/lib/lib64 /usr/lib64' -Dglibpth='/lib/lib64 /usr/lib64' -Dlibpth='/lib/lib64 /usr/lib64'
