I guess it will, at least give better error messages... ;-)

Cygwin or in a virtual machine?

In any case, don't try to install the uppercase version (TOPCOM), since
this is the "old-style" package, while "topcom" is the "new-style" one.

I.e., try

    ./sage -i topcom

(If you perhaps have issues accessing the internet from within the VM,
just download the new-style package's "upstream tarball" [1] in other
ways, and copy it into the upstream/ folder of your Sage installation
*before* doing './sage -i topcom'.  I would actually try that first.)

For Sage 7.3, it's the slightly newer version:
