Syntax error - LIBOSMOCORE

Hi list, sorry for this tedious question. I've already read a previous post about my problem but has not been useful ( http://lists.osmocom.org/pipermail/baseband-devel/2011-October/002351.html). I've this error after the make: checking for ranlib... ranlib ./configure: line 3508: syntax error near unexpected token `LIBOSMOCORE,' ./configure: line 3508: `PKG_CHECK_MODULES(LIBOSMOCORE, libosmocore)' make: *** [host/layer23/Makefile] Error 2 My settings with the last versions of sources: - Linux ubuntu 2.6.38-11-generic-pae #50-Ubuntu SMP Mon Sep 12 22:21:04 UTC 2011 i686 i686 i386 GNU/Linux - PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/root/cell_logger/tool-chain/install/bin - arm-elf-gcc -v (installed with http://bb.osmocom.org/trac/wiki/GnuArmToolchain) Using built-in specs.
