[Nix-dev] Nix failed to build on FreeBSD 9.1

[Henry Lenzi]

Hello -

I pulled sources today with git, everything was fine and dandy (I
followed the instructions), but somehow it just won't build, there's
some complaining about flex.

Included is the error log.

Can you help? It must be a trivial thing, but I don't really grok Flex.


TIA,
Hank

BTW: Failed to mention the following dependency in Nix's installation
chapter: Perl's WWW::Curl
(on FreeBSD, that's port named p5-WWW-Curl).
