missing library when building only rls-preview

[hyperfekt]

Trying to execute rls after building it with latest.rustChannels.[stable|nightly].rls-preview fails with rls: error while loading shared libraries: librustc_driver-a7268cc1add3f195.so: cannot open shared object file: No such file or directory.

I also have this issue:

error while loading shared libraries: librustc_driver-025268cc2660894c.so: cannot open shared object file: No such file or directory

A quick hotfix that I found that should work is adding ${rustc}/lib to LD_LIBRARY_PATH. That said, I now have a can't find crate for 'std' problem which isn't much better.

looks like we would need to wrap rls-preview package with LD_LIBRARY_PATH with few new paths.

Running ldd ./result/bin/rls i get:

Looks like few libs are missing.

Somebody want to fix this? You would need to know how to override rls-preview in a custom overlay and wrap rls command with wrapProgram --prefix LD_LIBRARY_PATH : "${rustc}/lib:..."

Actually, just using the rust package for the rustPlatform seemed to work. Can't check right now though.
