Autoconf / Automake ... suck.
Thats my conclusion after trying to get my streaming MP3 server to use them.
I know how usefull, and nice, it is to be able to download foo-src, and just have to type:
./configure make su - make
But actually generating all the config.in, and recoding your software to us all those "#ifdef HAVESOCKET_H" defines is a real mess.
I hope somebody can come up with a better system, soon.
