The problem, as I understand it, is that uname(2) is being called to
find out the kernel version, by the binary.  NetBSD is returning 1.5. 
The binary is expecting a Linux kernel version number, in the 2.*
range.  It therefore thinks that your kernel is too old.

In -current, the sources have been modified to return a hard-coded
Linux version number when in emulation, which more accurately reflects
the emulation of Linux syscalls.
 
You could start by having a look at that.
