Re^2: "symbol lookup error" message help

Here's what I don't understand:
I ran the following:

> which cpanm
/bin/cpanm
> head -n 1 /bin/cpanm
#!/usr/bin/perl
[download]

I know that /usr/bin/perl on this machine is 5.26.3, yet if I look at the most recent cpanm build.log file, it says:

cpanm (App::cpanminus) 1.7044 on perl 5.026003 built for x86_64-linux-
+thread-multi
[download]

Why does the log file list perl version 5.026003 when /usr/bin/perl is 5.26.3?

Because `$]`, the variable containing the Perl version number has the value `5.026003`. See the documentation in perlvar.	[reply] [d/l] [select]
