Hi elui,
well, packages in the url are home made with mandrake common optimizations (-march=i586 -O2 -fomit-frame-pointer ...) and with the configure options which suit well to amule.
I generated with the same src-rpm: common rpm, gtk1 rpm, gtk2 rpm.
- common hold common files for gtk1 and gtk2 (like docs)
- gtk1 and gtk1-devel hold gtk1 libs
- gtk2 and gtk2-devel hold gtk2 libs
To avoid confusion, i ve only put the gtk1 packages on the given url
To be complete, this packages use update-alternatives system to manage symlink to wx-config (see man)
To resume, to install amule, u must install base and the common and gtk1 packages, and the corresponding devel one if u want to compile it
U can update wiki with them if u want, but problem is that this url is just temporary, so should be better to find before a permanent repository for them
http://www.amule.org packages are ok on Mandrake, just more general and not mdk optimized, so chose what do u like

you "must" nothing

Just you MUST NOT install wx packages from official Mdk

the polish
