RasMol-2.6b2

[Eugene Leitl <eugene.leitl.,at,.lrz.uni-muenchen.de>]

 Hi,
 I'm trying to get my SpaceOrb 360 (a cheap 6DOF device) going with LibOrb
     http://www.spacetec.com/product/profile/index.cfm?ProductID=154
     http://www.umr.edu/~johns/projects/liborb/
 using a modified RasMol-2.6b2 from
     http://www.in-machina.com/~reece/RasMol/
 Unfortunately, I'm running into the following problems during build:
 eugene.leitl.,at,.lrz:~/download/rasmol/RasMol-2.6b2 > make
 gcc -O2 -fno-strength-reduce     -I/usr/X11R6/include   -Dlinux -D__i386__
 -D_POSIX_C_SOURCE=199309L -D_POSIX_SOURCE -D_XOPEN_SOURCE=500L -D_BSD_SOURCE
 -D_SVID_SOURCE   -DFUNCPROTO=15 -DNARROWPROTO
 -DRASMOLDIR=\"/usr/X11R6/lib/rasmol/\" -DTHIRTYTWOBIT   -c rasmol.c -o
 rasmol.o
 rasmol.c:52: sys/termio.h: No such file or directory
 make: *** [rasmol.o] Error 1
 Before you ask: RasMol 2.7.1 builds just fine, unfortunately the patch
 is RasMol-2.6b2-spaceorb-01.patch only applicable on RasMol-2.6b2.
 I seem to recall there is an easy fix for this, but I don't remember
 the specifics. I've tried some websearches, but so far found anything.
 Can anyone help?
 TIA,
 Regards,
 Eugene Leitl
