Cannot build libosmocore git master for debian 7.8

I'm trying to make a Docker image to install network in a box and am having some trouble getting libosmocore to build. apt-get update && apt-get -y upgrade && apt-get -y install wget libopencore-amrwb0 libopencore-amrnb0 libortp8 libortp-dev libopencore-amrnb-dev libopencore-amrwb-dev sqlite3 libdbi-dev libdbi1 libdbd-sqlite3 git build-essential automake libtool libpcsclite1 libpcsclite-dev then: git clone git://git.osmocom.org/libosmocore.git cd libosmocore autoreconf -i ./configure The error I'm currently getting is: checking whether struct tm has tm_gmtoff member... yes ./configure: line 12023: syntax error near unexpected token `PCSC,' ./configure: line 12023: ` PKG_CHECK_MODULES(PCSC, libpcsclite)' Any advice? Thanks, Stephen
