Comment (by Peter_Dyballa@…):

 Trying `port -vd upgrade unbound configure.compiler=gcc-4.2` configure now
 found:

 }}}

 and port succeeded to build unbound. It reported:

 {{{
 Error: The following dependencies were not installed: apple-gcc42
 }}}

 when I tried to use `configure.compiler=apple-gcc-4.2`. Success also when
 I tried to use Clang 3.4, which emitted a few extra warnings:

 {{{
 clang: warning: argument unused during compilation: '-pthread'
 }}}

 Both, GCC 4.2 from Xcode and Clang 3.4, reported:

 {{{
 libtool: install: warning: remember to run `libtool --finish
 /opt/local/lib'
 }}}

 Since I could easily remove unbound, i.e. there is no port that depends on
 it, why was unbound installed automatically? I did not know of unbound
 before so I never would have tried to install it.

 Is it necessary to install the package apple-gcc42 and try another build?
