Hi all,

I would like to do some correlation analysis in perl. Basically, that just takes a pair of arrays and gives a measure of their "similarity" on a scale -1 to 1.

I found the Math::NumberCruncher module that does exactly this. All seemed good and well. When I use Math::NumberCruncher; I got this:

C:\dev>perl -w -mMath::NumberCruncher
Can't locate object method "copy" via package "Math::BigFloat" (perhap
+s you forgot to load "Math::BigFloat"?) at C:/Perl/site/lib/Math/Numb
+erCruncher.pm line 33.
Compilation failed in require.
BEGIN failed--compilation aborted.

Now I'm at a bit of a loss on how to debug this. I have perl/site/lib/Math/BigFloat.pm on my machine. Any suggestions where to look would be very welcome!
