ADOM for Linux with NotEye depends on libvga.so.1, which on Debian 6+7* is provided by the libsvga1 package. However, this package has been removed[1][2] from Unstable and Testing (what will be Debian 8 some time in 2015). So it affects those who run testing/unstable (like me on my laptop) now, though it won't affect Debian 6 or 7 users ever, at least until everyone is off of them.
Apparently, use of this library is frowned upon by some:

So this is a warning that some other method, or way of providing libvga.so.1, may need to be found on Linux. I haven't found any evidence Ubuntu is also removing libsvga1, but as they generally follow Debian, they could as well.
* As of this submission: Debian 6 is aka Squeeze and Oldstable; Debian 7 is aka Wheezy and Stable; Debian 8 is aka Jessie and Testing; and as always, Debian Unstable is aka Sid.
