 So, it looks like the real fix might be to adjust
 pkgsrc/mk/compiler/gcc.mk to add something like these lines:
 
 .if !empty(USE_LANGUAGES:Mc++0x)
 GCC_REQD+=3D  4.4
 _WRAP_EXTRA_ARGS.CXX+=3D   -std=3Dc++0x
 .endif
 
 and then add to the pkgsrc/devel/boost-libs/Makefile this line:
 USE_LANGUAGES+=3D  c++0x
 
 Trouble is this then requires at least gcc 4.4 to build boost-libs,
 while in reality they build fine with 3.4.6... a bit of chicken and
 egg, since we'd like to check CC_VERSION to see which compiler version
 we have and then if we have gcc-4.4+ add the USE_LANGUAGES+=3D  c++0x...
 but it is not clear if there is a clean way to do that since
 mk/compiler.mk sets CC_VERSION and so it can't also later act on
 USE_LANGUAGES.
 
 A short term work around is to simply add:
 .if !empty(CC_VERSION:Mgcc-4.4.*)
 _WRAP_EXTRA_ARGS.CXX+=3D   -std=3Dc++0x
 .endif
 to the pkgsrc/devel/boost-libs/Makefile but I think this should not be
 added to the cvs repo because the _WRAP_EXTRA_ARGS.CXX is likely
 intended to be internal to pkgsrc/mk/...
 
 Can anyone else comment on this?
