What O/S are you using ?. You need Mandrake for the MDK_9.2-10 RPM version. I have just installed that one myself.
You should be able to use the .bz2 version. use these commands:
bunzip2 aMule-1.2.6.tar.bz2 ( this will unzip the file to a .tar file)
tar -xfv aMule-1.2.6.tar (this will extract the tarred files and create a dir called aMule-1.2.6)
cd to that dir and type
./configure ( you will see a scrolling list on your screen- if no errors then type )
make ( if no errors type)
make install ( to install the program if all goes well you have just compiled and installed aMule

)
cheers
