Bluefish fails to build, failing with:

The build seems to fail in the same way on Intel and Apple Silicon. Full build log attached

The error in the log is:

Newer compilers error about this sort of thing whereas older compilers let it slide with just a warning.

This is the upstream bug report: ​https://sourceforge.net/p/bluefish/tickets/66

Here's the fix: ​https://sourceforge.net/p/bluefish/code/8905/

The fix is included in bluefish 2.2.15 to which I will update the port.

[ryandesign (Ryan Carsten Schmidt)]

In c3bbf3e9552ede073a0e6704298e36947a89e3e0/macports-ports (master):

bluefish: Update to 2.2.15

Also switch to enchant2 and python312.

Closes: #70492
