[q-lang-users] sum not working (x86_64 / linux)

[Ethan G. <ee...@fa...>]

Hiyos. I just installed Q today, submitting a Source Mage GNU/Linux
'spell' for it, so that's one more distro that carries Q.

At least one function, sum, is not working. The manual gives the
following example:
==> sum [1..123456]
7620753696

I entered something similar with different results:
==> sum [1..100]
sum
[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100]

simpler uses of sum do not work either:
==> sum 1 2
sum 1 2

The splash text may be of interest:
0 ethan@vardo q-pure (0) $ q
def: error loading module
Warning: 141 unresolved external symbols

==> 

What is this module "def"? There is no such file either in the source
tree or installed. I assume a syntax error leading to a bad import
statement, but how can a nonexistant file have line numbers?

Testing the install did not produce anything useful:
0 ethan@vardo q-7.11 (0) $ q test.q 
Segmentation fault

wow.. wondering how to make it more general and less hard-coded is making my head hurt. that's a good sign that it's my code
