[Swarm-support] Swarm packages for Ubuntu 13.10/14.04

[Paul Johnson]

Hooray.

I thought this was going to be like the old days when I had to write and 
beg for help. Not so fast. I think I've got it.

Today I've been building and testing Swarm-2.4.1 on various Ubuntu.  I 
believe all problems are solved, I've written out all details here. If 
these fixes don't work for you, let me know and I'll try to replicate.

I wrote it out here

In the end, the Swarm apps still can run. There are shared library and 
compiler flag woes. But alls well that ends well.

One must replace the blt packages provided by Ubuntu with the ones I 
offer. This is necessary because Swarm is trained to tcl/tk 8.5 and we 
need BLT to keep its attention in that version. It must not wander over 
to the 8.6 side of things. If you ignore this advice, the error you get 
is one that we have seen since 1997: TKExtra instance: no such key

Another wrinkle is the Debian/Ubuntu multilib directory structure.  Now, 
They use /usr/lib/i386-linux-gnu and /usr/lib/amd86_64-linux-gnu. The 
Swarm configure statement in 2.4.1 was set to look for dynamic libraries 
in /usr/lib, /usr/local/lib, /usr/lib32 and /usr/lib64. I took the easy 
road by just editing the Swarm configure script and putting in the path. 
One of my long-standing embarrassments is that I just don't understand 
GNU automake/autoconf setups and I don't know how to make those changes 
in the underlying specification. But I'm pretty sure somebody who does 
understand that would understand what I'm saying and know what to do.

The other wrinkle is the gcc linker.  I can't understand why this crops 
up just now, but the compiler is stricter. If one uses  a math function 
like pow or sin, it was not previously necessary to explicitly link in 
the math library. gcc would just find it.  They have eliminated that 
convenience, and "-lm" must be added as a flag.
