Stop in /usr/ports/devel/icu.

Building with gcc (base) is succesful.

Looks like there's a problem with the configure script, it detects gcc but it's actually clang.

checking whether we are using the GNU C compiler... yes
checking whether clang accepts -g... yes
checking for clang option to accept ISO C89... none needed
checking whether we are using the GNU C++ compiler... yes
checking whether clang++ accepts -g... yes
checking how to run the C preprocessor... clang-cpp
