gcc47 @4.7.4_7 fails to build on Snow Leopard, Mac OS X 10.6.8, because "file not found: non-weak"

[ballapete (Peter "Pete" Dyballa)]

Some configure invocation checked for weak in assembler without success. The failure is:

[kencu (Ken)]

for me, this was fixed when Jeremy fixed this <​https://github.com/macports/macports-ports/commit/9d47963e77f12382350c5dbeca25a3a497b78065>. Try syncing and building again. (Of course, you will still get the isl and texinfo errors until they get repaired, but you shouldn't get this one any more).

[ballapete (Peter "Pete" Dyballa)]

It is built now.
