Comment (by mcandre):

 Update:

 The specific error I'm getting is

 {{{
 $ cabal install HLint
 ...
 ghc: mmap 131072 bytes at 0x0: Operation not permitted
 }}}

 This happens in HardenedBSD, does not happen in FreeBSD. This happens when
 ghc tries to build HLint's haskell-src-exts, uniplate, and/or aeson
 dependency libraries. This does not happen in HardenedBSD for smaller
 package trees like shake or QuickCheck.

 I tried adding swap space to provide a larger memory pool, but top showed
 cabal/ghc never dipping into swap space, so I suppose this mmap error
 means something else besides out-of-memory.
