Subject:

"Recursive dependency detected" without a cycle

While trying to test (not install) JANDREW/Spreadsheet-Reader-ExcelXML-v0.2.0.tar.gz I observe the following: ... Recursive dependency detected: Test::Fatal (have: N/A; want: 0.014) => RJBS/Test-Fatal-0.014.tar.gz => ExtUtils::MakeMaker (have: 6.98; build_requires: 0) => BINGOS/ExtUtils-MakeMaker-7.16.tar.gz => ExtUtils::MakeMaker (have: 6.98; build_requires: 0). Cannot resolve. DROLSKY/Module-Implementation-0.09.tar.gz [depend] -- NOT OK ... I don't see a cycle here. CPAN.pm is the latest stable (2.10), but it seems to happen also with 2.12-TRIAL. (If you need more information --- I'll try to preserve this perl as is (5.20.3D @ eserte.dev4.bbbike.org))

There appears to be two parts to this. First is that ExtUtils::MakeMaker is listing a build requires on itself. This is incorrect, even if the version required is 0. It is a regression in recent versions, and has been fixed in EUMM git. Second is that CPAN.pm is getting confused about the circular dependency. This seems to be because Spreadsheet-Reader-ExcelXML requires EUMM 7.04, so CPAN internally is treating that as the requirement for all EUMM prereqs. And since this is a test run, EUMM is never installed even though it gets processed first, and CPAN.pm doesn't believe it has been satisfied.
