pdftk fails compiling on yosemite due to gcc47 errors

[jjfPCSI1 (Jean-Julien Joseph Fleck)]

I'm trying to install pdftk on Yosemite (10.10) using Xcode 6.1 and it fails when building gcc47. The error log shows that it's experiencing #43978 but the fix given (i.e. upgrade to gcc48...) won't work as there is no +gcc48 variant in the pdftk port I tried to manually modify the port to add this variant but it failed compiling pdftk invoking java errors (which seems "normal" from what I've been reading on different tickets, for example #40058). Thus, would it be possible either to upgrade pdftk so that it could use gcc48 (but it seems quite difficult) or patch gcc47 so that it compiles on yosemite too (which seems easier) ? I would need it working within a week and would prefer not to instal pdftk from outside of MacPorts as suggested in #40058

Thanks
