3536	ghci doesn't resolve libm symbols properly on Windows	augustss		"The erf package on hackage uses the libm functions erf and erfc.
This all works fine in ghc, but in ghci we get an error.

To repeat:
{{{
cabal install erf
}}}
Try compiling
{{{
import Data.Number.Erf
main = print $ erf (1::Double)
}}}
and it works fine.
Now try
{{{
ghci
:m +Data.Number.Erf
print $ erf (1::Double)
}}}
and the result is
{{{
