This:

      (eval-when-compile
        (concat "\\(" lojban-c-rgx "\\)\\1"))

is the culprit. This is evaluated before compiling the file, when the
defconst is not defined yet. 

Considering `lojban-c-rgx' is a constant, I'm not sure why
`eval-when-compile' would be better than defining the result as a new
constant.

In any case, a poor man's fix could be replacing `eval-when-compile'
with `progn', or

    (concat "\\(" lojban-c-rgx "\\)\\1")

with

    "\\([bcdfgj-npr-tvxz]\\)\\1"

Also,

+    (synopsis "Emacs utilities for operating on lojban text")
+    (description
+     "lojban.el is an emacs library of functions, variables, regexps and
+interactive commands for handling lojban text.")

I would capitalize Emacs, and Lojban.
