Comple error in std.experimental.logger.core.d

[Chris Piker via Digitalmars-d-learn]

Using DMD64 (v2.068.2) on Linux CentOS 6.7, compiler was 
downloaded
from this link:

http://downloads.dlang.org/releases/2.x/2.068.2/dmd-2.068.2-0.fedora.x86_64.rpm

I get the following compile errors from the experimental logger 
class:

/usr/include/dmd/phobos/std/experimental/logger/core.d(702): 
Error: long has no effect in expression (cast(ubyte)160u)

/usr/include/dmd/phobos/std/experimental/logger/core.d(700): 
Error: long has no effect in expression (cast(ubyte)128u)

/usr/include/dmd/phobos/std/experimental/logger/core.d(698): 
Error: long has no effect in expression (cast(ubyte)96u)

... etc. going on for each instance of the enum core.LogLevel 
that I use
in my code.

Has anyone else seen this problem with the newest DMD?  Also, is 
there a work around.  I'm happy to provide any further 
information desired to debug the problem as I'm trying to bring D 
into my worksite to replace code that we've previously written 
using a combination of Python and C.

Thanks
