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

system$ 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 :

/home/perl/5.10/lib/site_perl/5.10.1$ rm –rf LWP*

or try with option "--no-lwp"

Example: 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'
