#88 zbar install for CentOS?

[Steve B.]

The configure script in the tarball has a shortcoming on CentOS; it looks for pygtk2.0, and in the CentOS repositories this is labeled as pygtk2. I modified the configure script to accept that, but for it to run I also needed to fix up pkg-config by doing an export PKG_CONFIG_PATH=/usr/lib64/pkgconfig for pkg-config to work (I suspect that should not be necessary...)

I also needed to set up prerequisite packages:
yum install gtk2-devel pygtk2 pygtk2-devel qt qt-devel
