+During interactive linking, GHCi couldn't find the following symbol:
+  /tmp/ghc879140_0/libghc_13.so: undefined symbol: some_c_function
+This may be due to you not asking GHCi to load extra object files,
+archives or DLLs needed by your current session.  Restart GHCi, specifying
+the missing library using the -L/path/to/object/dir and -lmissinglibname
+flags, or simply by naming the relevant files on the GHCi command line.
+Alternatively, this link failure might indicate a bug in GHCi.
+If you suspect the latter, please report this as a GHC bug:
