Hi,
Re-read the announcement another time !

"NOTE:You must use BOTH aMule and wx packages provided here, and desinstall all other previous wx and aMule packages to avoid conflict."
is for Mandrake RPM which use 2.5.3 wx, which will conflict if u have 2.4.2.
To resume: aMule is compiled against wx, so the couple amule+wx must agree at compilation time AND installation time.
If u compile urself, no prob
If u install package, u must avoid couple mismatch between wx and amule
