--- Comment #1 from Jan Beich (mail not working) <jbeich@FreeBSD.org> ---
Likely obsoleted by ports r426908. Even if not, please, describe build
environment in more detail e.g., backed by poudriere logs and if there're l=
ocal
patches. Don't forget to quote errors which are crucial when remuving cruft=
 in
future.

Also, if the compiler is buggy it should be patched rather than stacking mo=
re
hacks into consumers. While GCC 4.2 in base can't be patched retroactively =
the
ports can and *should*.

devel/boost-libs is fragile if consumers are built with different compiler =
or
flags. Adding -std=3Dgnu++11 would require an exp-run. Besides, GCC in base
doesn't support C++11
