write output from package build failure

[kevinushey]

I saw the following when installing devtools on an Ubuntu 22.04 VM:

> pak::pkg_install("devtools")

Compare to a plain install.packages() invocation:

It would be helpful if pak echoed the output from the configure script here.

Type .Last.error, that souls show the error.

Thanks, you're right:

Should pak include that as part of the output? That is, instead of just:

Type .Last.error.trace to see where the error occurred

pak could also print:

Type .Last.error to print the last error
Type .Last.error.trace to see where the error occurred

[gaborcsardi]

The error now includes the trace, I believe.
