Description Anthony Basile gentoo-dev 2012-09-25 23:44:33 UTC 
On systems without locale support, such as uclibc when configure without it, boost fails to build.  And yet there is a configuration option in boost's build system that allows you to disable locale: --without-locale.  It is a simple matter to expose this option to the user:

Comment 1 Anthony Basile gentoo-dev 2012-09-25 23:49:34 UTC 
Two other points:

1) locale is a local use flag and needs to be added to metadata.xml

2) If there is a good reason to force locale on for glibc, then we can add logic to check if has_version sys-libs/glibc and then act accordingly.
Comment 2 Arfrever Frehtes Taifersar Arahesis 2012-09-26 03:51:36 UTC 
Boost.Locale library was introduced in Boost 1.48.

Maybe modularization would better solve this this bug.
Comment 3 Diego Elio Pettenò (RETIRED) gentoo-dev 2012-10-31 16:38:17 UTC 
There is no reason to use has_version, we should just use package.use.force.

Fixed, the USE flag is nls and is present in 1.52.0-r2.
