Downloading https://github.com/PMunch/futhark using git
   Warning: Package 'futhark' has an incorrect structure. The top level of the package source directory should contain at most one module, named 'futhark.nim', but a file named 'opir.nim' was found. This will be an error in the future.
      Hint: If this is the primary source file in the package, rename it to 'futhark.nim'. If it's a source file required by the main module, or if it is one of several modules exposed by 'futhark', then move it into a 'futhark/' subdirectory. If it's a test file or otherwise not required to build the the package 'futhark.nim', prevent its installation by adding `skipFiles = @["opir.nim"]` to the .nimble file. See https://github.com/nim-lang/nimble#libraries for more info.

Hawe you read through the other related issues? This is simply a dynamic library search path issue. If you have clang installed as well you should be able to simply add --passL:"$(clang -print-file-name=libclang.so)/.." or similar. The open PR might also automatically fix this issue for you.
