DictEm - Dictionary client for Emacs

I found an error when compiled on my gentoo installation with emacs-22.2.
actually it is possible to load the package and use it, but customization
interface is broken, this appears after M-x customize-group dictem:

/- DictEm group: ----------------------------\
State: UNKNOWN, you should not see this.
Client for accessing the DICT server.
Dictem Server: %]

please take a look on the compilation errors below:
