Patch from Boost Trac ticket #2499 is attached. I also am including it in my boost-overlay (see bgo #234902).
Created attachment 171779 [details, diff] Patch from Boost Trac #2499
Unfortunately, that particular patch has bizarre whitespace issues that prevent it from applying with the flags that epatch runs patch with. If there's a way to tell epatch to pass -l to patch, that'd do the trick; I can't seem to eliminate the whitespace that's causing patch to choke though. Also, another version of the patch can be found in Boost Trac #2494, I'll try that and see if it applies cleanly using the "standard" flags.
Whoomp, I better back up: With the help of twkm off of Freenode's ##workingset channel, a fixed version of the patch DOES exist. (Silly me didn't notice 'til now :P) Uploading now.
AGGH! Looks like I'll have to use -l after all *sigh*
Finally, a working version of the patch is here, thanks to the efforts of twkm from ##workingset and desultory from #gentoo-dev-help!

The patch does not work for me. I added it after all other epatch lines in the ebuild.
Included in boost-1.37.0-r1 which is in the tree. Thanks everyone!
