I ran into this as well tonight, and boost did build with the +clang90 variant...

but then the icu update broke all the clangs, so now I'm trying to sort that out, rebuild clang against the new icu, then rebuild boost with the new clang.

I just got the same output/errors.

I have the same problem. I was hoping that upgrading to Macports 2.6.2 from 2.6.1 would fix the problem. But it did not. If anyone know a workaround, please let me know. Thanks.

sudo port -v upgrade boost +clang90

See comment:8:ticket:59217. I got it installed last week on 10.6 at least.

I would like to fix it, but this requires #58898 to be resolved, else you always need manual intervention (including on the buildbot).

Thanks to both of you for working on this. What is the preferred action right now? Ken's solution?

[lemzwerg (Werner Lemberg)]

I tried Ken's suggestion from comment:7, and it worked, thanks!

boost now builds on Lion without any interventions or added variants:

$ port -v installed boost

Nice! Thanks for reporting your success, @kencu!
