The problem that I've found when I was trying to port my installer to FreeBSD was their make doesn't like GNU Makefiles. Not sure when they diverged from one another so having Make everywhere, doesn't necessary mean your Makefile will work everywhere.

I liked how security centric FreeBSD was but they seem to be anti-enterprise friendly. The process to install Oracle Java was painful and EnterpriseDB didn't even bother creating a Postgres installer for it. Maybe the freedom that the BSD license offers, is making their environment too stagnant when compared to GNU and Linux.
