Comment (by NicosPavlov):

 I am afraid I can't reproduce that error, but from the log, it seems that
 you are employing a non-compliant compiler:
 {{{
 :warn:configure All compilers are either blacklisted or unavailable;
 defaulting to first fallback option
 :debug:configure Environment:
 :debug:configure CC='/usr/bin/cc'
 :debug:configure CC_PRINT_OPTIONS='YES'
 :debug:configure
 CC_PRINT_OPTIONS_FILE='/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_kde_kdevplatform/kdevplatform/work/.CC_PRINT_OPTIONS'
 :debug:configure CFLAGS='-pipe -Os'
 :debug:configure CPATH='/opt/local/include'
 :debug:configure CXX='/usr/bin/c++'
 }}}

 As kdevelop requires c++11, I assume clang or at least a compiler
 compatible with libc++ should be employed. The errors in the log point to
 the same problem.
