Errore installando amule cvs

[jimthelizard]

Buonasera a tutti.
Ho installato le wxwidgets 2.8.7 però installando amule cvs ho sempre questo errore (dando sudo make install) :

/usr/include/wx-2.8/wx/protocol/http.h:21: warning: dereferencing type-punned pointer will break strict-aliasing rules
./Scanner.l: In function ‘void LexFree()’:
./Scanner.l:191: error: ‘yylex_destroy’ was not declared in this scope
Scanner.cpp: At global scope:
Scanner.cpp warning: ‘void yy_fatal_error(const char*)’ defined but not used
make[2]: *** [libmuleappcore_a-Scanner.o] Error 1
make[2]: Leaving directory `/home/pippo/amule-cvs/src'
make[1]: *** [install-recursive] Error 1
make[1]: Leaving directory `/home/pippo/amule-cvs/src'
make: *** [install-recursive] Error 1

Da cosa può dipendere e come porre rimedio ?
Grazie infinite
Buona serata.
