[install-discuss] how do I find out which package contains /usr/sfw/lib/libstdc++.so.6.0.3?

[Kostas Oikonomou]

Hi,

I am running b125 on AMD64, and I have the suspicion that 
/usr/sfw/lib/libstdc++.so.6.0.3 is causing me some problems 
with Opera.

How do I find out which package contains it so I can try 
uninstalling it?

And more generally, how do I find out which package contains 
a particular file?  The "pkg" man page doesn't seem to anwer 
this question.

Thanks.
