fpm has had multiple Ruby gem dependency issues, and nfpm has better support
for code signing if we wanted to do that in the future. The rest of the
platforms may be migrated to nfpm later.
In Debian 11, Pango now depends on PCRE2, so R 3.x will not be compiled with
Pango support if we hide PCRE2 to prevent R 3.5 and 3.6 from taking an unnecessary
dependency on PCRE2.
To check if R 3.x was compiled without Pango support, look for this line in the
configure output:
checking whether pkg-config knows about cairo and pango... no
Or in R, check if the "bitmapType" option defaults to "Xlib" instead of "Cairo":
> getOption("bitmapType")
"Xlib"
