Tried it on an Acer Chromebook R13 running Version 69.0.3497.35 
(Official Build) dev (32-bit). I have no previous experience with 
llvm.

dub init ran fine.

getting this error when trying to run dub in the newly created 
project
chronos at localhost ~/work/my_test $ dub
Failed to invoke the compiler /usr/local/bin/ldc2 to determine 
the build platform: /usr/local/bin/ldc2: error while loading 
shared libraries: libLLVMLTO.so.5: cannot open shared object 
file: No such file or directory

when running ldc2

chronos at localhost ~/work/my_test $ ldc2
ldc2: error while loading shared libraries: libLLVMLTO.so.5: 
cannot open shared object file: No such file or directory


I do have another version installed though:

chronos at localhost ~/work/my_test $ locate libLLVMLTO
/mnt/stateful_partition/dev_image/lib/libLLVMLTO.so
/mnt/stateful_partition/dev_image/lib/libLLVMLTO.so.6
/mnt/stateful_partition/dev_image/lib/libLLVMLTO.so.6.0.0
/usr/local/lib/libLLVMLTO.so
/usr/local/lib/libLLVMLTO.so.6
/usr/local/lib/libLLVMLTO.so.6.0.0


trying to build ldc:

chronos at localhost ~/work/my_test $ crew build ldc
(i) ldc: D language compiler using LLVM.
