thanks for your clues.
Anyway, I am stucked on the same level after autogen.sh it prits:
configure.in:104: error: possibly undefined macro: AC_LIBTOOL_WIN32_DLL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
configure.in:105: error: possibly undefined macro: AC_PROG_LIBTOOL
autoreconf: /usr/bin/autoconf failed with exit status: 1
It is still on the level of compiling puredata 0.45.4
Possibly the same will happen while compiling Gem too.
How should I fix this m4_pattern_allow?

Meanwhile I downgraded to Ubuntu 12.04.
