EPoll is now available, but epoll.h is missing #include <sys/stdint.h>
wesolows suggested that a lofs mount would let me alter the content of that file.
I could create a corrected epoll.h and lofs mount it into my builder zones.
20140501T225642Z and 20140515T211957Z are the only affected platform images. Hopefully the next release will include a fix for this.
