I see

and the resulting pkgr install takes about 2.2 seconds, which isn't nearly enough to install from source. This is pkgr 2.0.1:

➜  /tmp pkgr | grep version
pkgr cli version v2.0.1

can you run plan with a loglevel of debug - I'm unable to reproduce - and I see source when i run.

in addition with debug you'll see the installer information

It appears that this may be a caching issue. If I run pkgr clean cache and then repeat the above steps, it takes 42 seconds, and with --loglevel=debug I see the various compilation messages. So, what seems to be happening is that if a source package is installed, pkgr builds the binary and caches that built binary. A subsequent call to pkgr install appears to simply install this binary. Is that what is actually happening?
