[ESS] problem with developer-mode

[Andreas Leha]

Hi,

since an update to recent git version (ess-version : 13.03 [<unknown>],
commit 003d9784446ca5916f2c78c90c4b47d461a8119) I get problems with
developer-mode:

When I run ess-eval-function in a developed package, I get
,----
| Fehler in eval({ (from #2) : konnte Funktion ".essDev_source" nicht finden
`----
(Sorry for the German:  Can't find function ".essDev_source")

Regards,
Andreas
