the libicu in brew now builds with c++11 by default if its available, which means boost 1.52 fails to build with --build-from-source (which I need because I want to bind against the brew python, not the system one).
Undefined symbols for architecture x86_64:
"icu_50::UnicodeString::doReplace(int, int, unsigned short const*, int, int)", referenced from:
boost::locale::impl_icu::strftime_to_icu(icu_50::UnicodeString const&, icu_50::Locale const&) in formatter.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
This seems to be because libicuuc has been created with the c++11 type "char16_t":

This seems to be because libicuuc has been created with the c++11 type "char16_t":
~ nm /usr/local/Cellar/icu4c/50.1/lib/libicuuc.50.1.dylib | grep doReplace | c++filt 00000000000418bc T icu_50::UnicodeString::doReplace(int, int, char16_t const*, int, int) 0000000000043bd2 T icu_50::UnicodeString::doReplace(int, int, icu_50::UnicodeString const&, int, int)
which apparently doesn't match unsigned short const*.
there doesn't appear to be an obvious way to tell libicu to stop doing that short of patching the configure script.
the way I resolved this is to do
but obviously itd be nice if it worked out of the box
