[Telepathy] telepathy-sofiasip-0.5.14 autconf: undefined macro: AS_VERSION

[Frederik Himpe]

When running autoconf in telepathy-sofiasip-0.5.14, I get this error:

configure.ac:16: error: possibly undefined macro: AS_VERSION
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
configure.ac:31: error: possibly undefined macro: AS_COMPILER_FLAG

$ autoconf --version
autoconf (GNU Autoconf) 2.63

What could be wrong here?
