I see that my latest release of Net::SCP::Expect is failing tests left and right, including Solaris. That's interesting, since it's Solaris that it was developed on.
I can only guess this is because my test script isn't really complete. I wanted to get this version out the door, though, because of that major bug that Ruban Phukan found (and jdavidb fixed).
Anyway, ignore the cpan test results until you see an actual bug report.
