in reply to Errors Installing REST::Client

Welcome. Net::SSLeay isn't installing. If you look at the README it states that the openssl devel should be installed, as per the prerequisites section.

When an automated module installation fails you should read the documentation for the modules which cause the failure. This includes open issues as well as the associated README/INSTALL files.

Try the above, install the devel package using your package manager, then try to install REST::Client. Report back any problems.

    I still can’t install the Net::SSLeay. The got past the original error. Here is what I have tried.

     First installed openssl and recompiled

cd /usr/local/src
wget https://www.openssl.org/source/openssl-1.0.2-latest.tar.gz # gett
+ing the openssl package
tar -zxf openssl-1.0.2-latest.tar.gz

# compiled and installed it. 
cd openssl-1.0.2a
 ./config
make
make test
make install

# moved old openssl and created openssl with symbolic link
mv /usr/bin/openssl /root/
ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl

    [download]

    At this point when I re-ran 'perl MakeFile.PL' and 'make test' for Net::SSLeay. I get the error can't find err.h file, to have it resolved. I created a symbolic like on where look for .h files as following.

     cd /usr/local/include
ln -s /usr/local/ssl/include/openssl

At this point I re-ran 'perl MakeFile.PL' for Net::SSLeay. Now it say

/usr/bin/ld: cannot find -lssl
/usr/bin/ld: cannot find -lcrypto
/usr/bin/ld: cannot find -lz
collect2: error: ld returned 1 exit status

      Excuse the late reply, installing openssl-devel via your package manager (as explained in the module README) will satisfy any required dependencies, then try reinstalling the perl module from cpan.
