value += is not a member of String

[apaj]

Hi,

I've been playing around with chipyard successfully in a previous version (3a83cd0, March 14), but after the update I did two days ago, I get the following errors for running make inside chipyard/sims/verilator:

[error] /home/user/chipyard/generators/testchipip/src/main/scala/Dromajo.scala:25:19: value += is not a member of String

There seem to be two types of issues here, but somehow I am feeling that both might have the same cause - hence here together. Correct me if I am wrong, though...
I see that @abejgonzalez did all the work in Dromajo.scala and most of work in TraceIO.scala, so I dare mentioning here - kindly forgive me.
Please, do you have any ideas what might be causing this behavior?
Thanks,
Aleksandar
