Subject: [PATCH] Fix debug build by adding a missing conditional import

`src/lib/Err.hs` conditionally uses `unsafePerfomIO` when `DEX_DEBUG` is
defined, but it doesn't `import System.IO.Unsafe`, so `unsafePerformIO`
is not defined. This can be fixed by importing that module when
`DEX_DEBUG` is defined.
