Why not write the following?

import os

def build(module,tag):
  os.system("cvs co %s %s" % (tag,module))

  cvs_dep = open("%s/cvsDependencies" % (module,),"r")

  for line in cvs_dep.xreadlines():
    (m,t) = line.split("<some separator you don't mention!>")
    build(m,t)

  os.chdir(module)
  os.system("make -DVERSION=\"%s\"" % (tag,))

build("my_module","-r v1.0")

That should do what you want, I guess...
