CPAN.pm includes the statement: 
use Text::ParseWords ();

It looks like the perl interpreter notices the existence of the namespace, and decides to invoke "install" as a method of that namespace.

Changing the spelling of the module slightly modifies the way perl parses it.

I don't know why.

I see the same effect when trying to "install" File::Basename or other "File::" modules used by CPAN. 

C:\Perl64\lib>perl -MO=Deparse -MCPAN -e "install File::Basename"
Set up gcc environment - gcc.exe (rubenvb-4.5.4) 4.5.4
use CPAN;
'File::Basename'->install;                 # Method call (unexpected)
-e syntax OK

-- change the name -----
C:\Perl64\lib>perl -MO=Deparse -MCPAN -e "install File::BasenameXXX"
Set up gcc environment - gcc.exe (rubenvb-4.5.4) 4.5.4
use CPAN;
install('File::BasenameXXX');                 ## What we expect
-e syntax OK
