devtools::install_git fails to install dependencies of packages in Depends or Imports

I have a package that depends on the package extrafont. If extrafont and its dependency Rttf2pt1 aren't present on the user's system, installation of my package fails. I have extrafont as "Depends" in my package's DESCRIPTION file. When I run devtools::install_git() to install my package from a URL, the output terminates with:

** preparing package for lazy loading
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
  there is no package called 'Rttf2pt1'
Error : package 'extrafont' could not be loaded
ERROR: lazy loading failed for package 'tntpr'
* removing 'C:/Users/SFirke/Documents/R/win-library/3.3/tntpr'

Looks like extrafont installs okay, but doesn't work because Rttf2pt1 is missing. When I add Rttf2pt1 to the Depends list in my DESCRIPTION file, then the installation succeeds, installing both extrafont and Rttf2pt1 and my package.

Why do I need to put Rttf2pt1 in my Depends list? It's present on the "Imports" list in the DESCRIPTION file from the extrafont package:

Depends:
    R (>= 2.15)
Imports:
    extrafontdb,
    grDevices,
    utils,
    Rttf2pt1

Additional info

When I run devtools::install_git("https://myurl.com/tntpr.git", dependencies = TRUE), I get the following output. It installs dplyr from GitHub, then extrafonts, then fails loading my package:

The problem: There are issues specific to Windows where both devtools 1.12.0 (the current CRAN version) and the current development version of devtools 1.12.0.9000 have trouble with nested / recursive dependencies (i.e., say your package A depends on package B which depends on package C; devtools functions install_*(A) will not install C).

See this comment re: the development version and the top parts of the thread that note problems with the CRAN version as well and this package's workaround of manually specifying sub-dependencies to install.

Solution: I installed an old version of devtools 1.11.1 (released April 2016), which works for my install_git() call above even when there are dependencies missing that need to be installed.

install.packages("devtools") # from CRAN
devtools::install_version("devtools", version = "1.11.1", repos = "http://cran.us.r-project.org") # get the old version

Then restart R and use devtools as intended.
