I'm building Android with Eclipse on Fedora 13.
aapt, zlib and R.java problems
I ran into the following error:
.../android-sdk-linux_x86/platform-tools/aapt: /lib/libz.so.1: no version information available (required by .../android-sdk-linux_x86/platform-tools/aapt)
The solution is described, beautifully at http://polywogsys.livejournal.com/286952.html
