Subject: | Module::Install::Can::can_run called without object |
...trying to install DCOPPIT/grepmail-5.3111.tar.gz under cygwin.
and running the topical..
perl Makefile.PL
It crashes into a call of ...
ExtUtils::MM_Cygwin::maybe_command("MM", undef)
what is the best way to fix that ?
- can we put $ENV{PATH} as a default search path?
- or we have some incompatibilities in calling the {::maybe_command}("MM") ? and then need to make the can_run more robust upfront?
thx
