| No, that is not an error. Look at the symbol "c:build-program". You

Aha!

| If you split the statement into two -eval forms, then first the
| compiler is loaded and then the second string is parsed into a lisp
| form and evaluated.

OK, thanks for the explanation.  Faré sent me similar explanation.

Thanks!
