Errors installing Online Price Retrieval

[Michael Seifert]

For anyone else having Date::Calc failing with the install of Online Price
Retrieval, here is the solution. Note there are open bugs in Date::Calc
which are responsible for it failing and are documented here:
https://rt.cpan.org/Public/Dist/Display.html?Name=Date-Calc

After a failed installation, I went to the
C:\strawberry\cpan\build\Date-Calc-6.3-XXXXXX\t directory and removed the 3
test files which failed. I replaced them with one of the test files which
succeeded (copied and then renamed f015.t to f016.t, f027.t and f028.t).

I ran the script again and paused the installation (good 'ol pause key),
copied the 3 test files from the old Date-Calc-6.3-XXXXXX\t directory to the
new Date-Calc-6.3-XXXXXX\t directory (each installation creates a new
directory and XXXXXX is a random unique string).

Now that the new Date-Calc-6.3-XXXXXX\t directory has the offending test
files replaced with ones that will pass, I un-paused the install (pressing
on the cmd.exe window) and it continued and succeeded.
