Missing lz4 for PPC

[michele.bert at posteo.net]

Hello.
Eventually I managed to install macports on my iBook-G4, by compiling 
sources of latest version.
Selfupdate completes flawlessly.
Next step is installing bash. It needs a bunch of dependencies, included 
lz4, but it has not been found. That's what log says:

----------------------

Indeed if I visit those urls, there isn't any file name containing 
"ppc".
Does it mean that such port is not supported any more on powerpc 
platforms? Or should I signal this behavior somewhere?
