It has restrictive bounds on `base` (which secretly means ghc). You can try
`--allow-newer` to see if it works with newer versions.

Oh woe, this package is sorely out of date.  Sadly --allow-newer is
too loose.  There are compile failures. Applying the patch below will
get a lot of it working with GHCs up to 9.2, although things that rely
on Network won't work (there is no longer a top-level Network module).

repa doesn't seem to work with any later GHC, but the bits that don't
depend on repa can probably be brought up to date with later GHCs.

Anyway, it's rather a mess.  Sorry about that.  Hope you can get at
least some use out of the below patch.
