Symbol 'type spatial.lang.InternalAliases' is missing from the classpath

[Hui Zhang]

Hello,

I just did 'git pull' on the master branch because previous Spatial is somehow not compiling my previous working code.. However, I failed in the first step, after I did `bin/spatial helloworld --synth --fpga=AWS_F1` (or  --sim)

[error] Symbol 'type spatial.lang.InternalAliases' is missing from the classpath.

[error] This symbol is required by 'trait spatial.lang.api.StaticAPI_Internal'.

[error] Make sure that type InternalAliases is in your classpath and check for conflicting dependencies with `-Ylog-classpath`.

[error] A full rebuild may help if 'StaticAPI_Internal.class' was compiled against an incompatible version of spatial.lang.

[error] one error found

[error] (spatial / Compile / compileIncremental) Compilation failed

Sorry, I didn't `make clean` before `make install` after `git pull`. Now the problem has gone.
