-All linux binaries are built in a chroot environment (Debian 6 "Squeeze"), while the windows binaries can be cross-compiled. The only packages required in the host OS are:
-
-    debootstrap git-core xz-utils build-essential mingw-w64 nsis
+Building is currently supported only on the current 64-bit Debian stable release (```wheezy```), but it should work on other Debian/Ubuntu releases as well. Please run ```scripts/setup-linux.sh``` as root, which will create all the chroot environments and configure them for building properly. A total of 4 chroot environments is created (approx 1GB will need to be downloaded):
+ * Debian-wheezy i386  (should work on Ubuntu 12.04 LTS and later)
+ * Debian-wheezy amd64 (should work on Ubuntu 12.04 LTS and later)
+ * CentOS-5 i386  (should work on systems where older GLIBC is installed)
+ * CentOS-5 amd64 (should work on systems where older GLIBC is installed)
