[Kolab-devel] erlang/rebar errors on guam

Hi,

I'm getting erlang errors when compiling guam:

#####
# DEBUG=1 rebar3 release --dev-mode false --relname guam --relvsn 0.9.0
--verbose
...
===> Running provider release
===> Uncaught error in rebar_core. Run with DEBUG=1 to see stacktrace or consult
 rebar3.crashdump
===> Uncaught error: {badmatch,false}
===> Stack trace to the error location:
[{rlx_util,load_file,3,[{file,"src/rlx_util.erl"},{line,180}]},
 {rlx_prv_assembler,render,2,[{file,"src/rlx_prv_assembler.erl"},{line,676}]},
 {rlx_prv_assembler,include_nodetool,1,
                    [{file,"src/rlx_prv_assembler.erl"},{line,672}]},

I'm not familiar with erlang. What does that mean?
