Fink Emacs lost control key after update

I use Emacs22 to write LaTeX files, together with AucTeX to compile them and
a dvi viewer all under Fink X11 on MacBook Pro Intel Leopard. It has worked perfectly for over a year.
Today I updated both Mac and Fink files and I lost control keys in Emacs.
When I press C (Ctrl, ^) key and nothing else Help appears:
"You have typed <f1>, the help character."
Ctrl apparently works normally in other applications. Any help would be appreciated. Very appreciated :-)
