Running Haskell script with Stack uses multiple versions of one package #1957
Description
Hello, there
In Snowdrift, we have a database setup script called sdb.hs. It uses
stack along with the turtle package to run as a quasi-shell script.
When I tried to run it today to start the database server, I got this
error message:
sdb.hs:70:47:
Couldn't match type ‘T.Text’
with ‘Text’
NB: ‘T.Text’
is defined in ‘Data.Text.Internal’ in package ‘text-1.2.2.1’
‘Text’ is defined in ‘Data.Text.Internal’ in package ‘text-1.2.2.0’
Expected type: String -> Text
Actual type: String -> T.Text
In the first argument of ‘map’, namely ‘T.pack’
In the second argument of ‘procs’, namely ‘(map T.pack as')’

As you can see, stack is using multiple versions of text, and coming up with this ridiculous error.
