I had a warn line 23 to investigate a litle bit, it seems at least that
coefficent y=ax+b are not what you are expecting (171.455755190058
instead of 87.1302565686522 ) ?
Is it a bug ? a precision problem (ia64) ? something I have done badly ?
I used perl -MCPAM -e shell to install.
Thanks for your help
