I tried compiling with both DMD 2.095.1 and LDC 1.25.1 and still 
got the linker errors.

Then I tried compiling with and older version of dub (version 
1.20.1 which  shipped with DMD 2.091.1) but compiling with DMD 
2.096.0 (`/opt/dmd.2.091.1/linux/bin64/dub build 
--compiler=/opt/dmd.2.096.0/linux/bin64/dmd`) and it compiled and 
linked just fine. So, this appears to be a dub problem.

After some additional testing, I found that this compiles with 
dub version 1.23.0 (shipped with DMD 2.094.1) but not with dub 
version 1.24.1 (shipped with DMD 2.095.1).

I ran `/opt/dmd.2.094.1/linux/bin64/dub build 
--compiler=/opt/dmd.2.096.0/linux/bin64/dmd -v` and 
`/opt/dmd.2.096.0/linux/bin64/dub build 
--compiler=/opt/dmd.2.096.0/linux/bin64/dmd -v` and diffed the 
compilation and linking commands. The linking commands are the 
same, but the compilation commands are different. The compilation 
command generated by the new version of dub is missing a number 
of files (from a library that I am importing) that the old 
version of dub includes. All of the places where I was getting 
linker errors are in these missing files.

I am working on creating a minimum test case using dustmite and 
will file an issue in the dub GitHub project. I will post a link 
to the issue here when I have created an the issue.

Thanks for your help!
