Compiling Crypto.Hash.MD5 eta.exe: panic! (the 'impossible' happened)

I added the package uuid:1.3.13 as a dependency to my project and while installing it the compiler gave me this error:

I am using gradle 4.7 with the etlas plugin on a Windows machine.

Hi and thanks to try eta!
It seems cryptohash-md5 package uses calls to c native code (with the ccall unsafe "value sha1.h hs_cryptohash_sha1_finalize") and i am afraid eta does not support it by design.
The fix usually involves create a patch for the package in the eta-hackage patch set, replacing the c calls with java ones. As uuid seems to be a useful package i've filled an issue to track the request for the patch: typelead/eta-hackage#90

@glhrmfrts thanks to the patchs done by @Jyothsnasrinivas the uuid package compilation should not fail with those errors, feel free to reopen of fill anothe issue if it still does not compile
