[Bug-glpk] tspsol: command not found

[? ?]

OS: ubuntu 9.10

          glpk 4.38-1

glpk-utils 4.38-1
/*
This package contains the following stand-alone tools:
   * glpsol: LP/MIP solver
   * tspsol: TSP solver
*/

but

$ tspsol -t **.tsp
$ tspsol: command not found

I failed to search <tspsol> in <glpk-utils>, and also can not find
<tspsol.c>. I have downloaded source code of <tspsol.c>, but it has too
many bugs to translate to <tspsol>. I wish that <tspsol> can be used in
my computer.
