Exactly what command were you using.

"cpan BPSCHUCK/Finance-Quote-1.64_03.tar.gz" would have installed the
interim version.

I was a Fortran IV/77 developer a lifetime ago. Learned Basic as part of
an advanced Math curriculum in 8th grade (1974-1975).

It's a known issue with AlphaVantage, noted in the Caveat section of the 
Finance::Quote::AlphaVantage(3) man page. The AV API does not return the 
currency, so all ".L" symbols are assumed to be GBP. If the user knows a 
security is traded in GPp/GBX, and using AlphaVantage, add a ".X" to the 
symbol. So NWG.L would be NWG.L.X.
