On Solaris 8, which doesn't support /dev/random, entropy.c doesn't compile. It has a missing signal.h include file.
Created attachment 1190 [details] patch to entropy.c
Sigh. Thanks for the report. It seems this doesn't happen when the host has either the /dev/random patch or prngd (which my test boxes do), even if you configure --with-rand-helper.
Patch applied, thanks. It will be in the next release.
Close resolved bugs after release.
