New description:

 A Haskell source file with an ANN pragma will fail to compile with -static
 if any packages do not have dynamic libraries installed.

 Reproduction:
 {{{
 $ echo "module Bug where {-# ANN module \"just a string\" #-}" > Bug.hs
 $ cabal sandbox init
 $ cabal install transformers-compat --disable-shared
 $ ghc -static -package db ./.cabal-sandbox/x86_64-linux-
 ghc-8.2.0.20170522-packages.conf.d  -package transformers-compat -c Bug.hs
 <command line>: can't load .so/.DLL for: libHStransformers-
 compat-0.5.1.4-DQiwI4tzfvoKHf8rERr8Q2.so (libHStransformers-
 compat-0.5.1.4-DQiwI4tzfvoKHf8rERr8Q2.so: cannot open shared object file:
 No such file or directory)
 $ cabal install transformers-compat --enable-shared --reinstall
 $ ghc -static -package db ./.cabal-sandbox/x86_64-linux-
 ghc-8.2.0.20170522-packages.conf.d  -package transformers-compat -c Bug.hs
 -fforce-recomp
 }}}
 Presumably the ANN pragma causes ghci to load with all libraries which
 must be dynamic.

 Not sure which category is correct for Type of failure.
