Please use the following steps to build and install Delve on Linux.
There are two ways to install on Linux. First is the standard go get method:
go get github.com/derekparker/delve/cmd/dlv
Alternatively, you can clone the repo and run:
$ make install
Note: If you are using Go 1.5 you must set GO15VENDOREXPERIMENT=1 before continuing. The GO15VENDOREXPERIMENT env var simply opts into the Go 1.5 Vendor Experiment.
