I installed build-essentials like mentioned on the site.
the installation is freezing when I get the following messages:

[nodegit] Fetching binary from S3.
[nodegit] Failed to install prebuilt, attempting compile.
[nodegit] Installing all devDependencies
[nodegit] Determining source dependencies.
[nodegit] Detecting vendor/libgit2.
