This should be defined in src/lib/endian.rb or error out if the PTRSIZE is unexpected. #if PTRSIZE == 8 #define ULONG_SWAP(w) UINT64_SWAP(w) #elif PTRSIZE == 4 #define ULONG_SWAP(w) UINT32_SWAP(w) #else #error "unexpected pointer size" #endif From your error it looks like it isn't defined at all and treated as a function. I don't know enough about ppc internals to help here, sorry.
net-p2p/gtk-gnutella-1.1.15 builds fine again on ppc. I suppose it's this one: https://github.com/gtk-gnutella/gtk-gnutella/commit/078de36a86b6f7af260f257e7a583f99947e6998
