The first release of LibreSSL portable has been released. LibreSSL can be found in the LibreSSL directory of your favorite OpenBSD mirror.
http://ftp.openbsd.org/pub/OpenBSD/LibreSSL has it, and other mirrors will soon.
libressl-2.0.0.tar.gz has been tested to build on various versions of Linux, Solaris, Mac OSX, and FreeBSD.
This is intended as an initial release to allow the community to start using and providing feedback. We will be adding support for other platforms as time and resources permit.
As always, donations (http://www.openbsdfoundation.org/donations.html) are appreciated to assist in our efforts.
