|There's more than one way to do things|
If you want more specific advice on how to fix these problems, then please let us know which operating system you are running and which version of perl you are running.
To get information about perl:perl -v
To get much more information about perl:perl -V
To get information about the operating system:uname -a
In case of Linux, also try:ls /etc/*version*
and if that lists a file, show its content:cat /etc/some-linux-distro-name-version
Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)
