but ive installed every dependency and made sure they are above the minimum version required

[root@gorf irssi-otr]# /usr/bin/autoconf --version
autoconf (GNU Autoconf) 2.69
[root@gorf irssi-otr]# /usr/local/bin/autoconf --version
autoconf (GNU Autoconf) 2.69

not sure what to do now. im on CentOS 6.7

You need libglib2.0-dev (Debian package name though) which installs the need .pc (pkgconfig) file for this macro to work. I'm guessing there is something similar to CentOS ?
