+On illumos you can configure a ipkg or sparse branded zone to host your
+pkgsrc tree. Since the software database is generally managed
+independently from the host, the same essential development tools,

+within the zone.

 General
 ------
 
+Sun Solaris and Illumos come by default with a mixed {32,64}-bit
+userland.  This can include the compiler, which may shipped as a
+32-bit ELF.  In this case, the compiler by default will create 32-bit
+executables and shared libraries, unless told otherwise.
+
 To build 64-bit binaries, pass '--abi=64' to bootstrap, and also see
 the crle(1) man page to configure the runtime linking environment.
-(It is not clear if this is the default on sparc64/amd64, and if not,
-why not.)
+64-bit runtime libraries can be usually found at /usr/lib/amd64.
+NB: passing '-m64' to the compiler is not needed when using --abi=64.
+
+It is unclear whether --abi=64 is still a requirement on some modern
+illumos distributions, which provide a 64bit compiler. Joyent doesn't
+mention it in their pkgsrc bootstrap guide for SmartOS.
 
 Generally, illumos-based distributions come with gcc, and gcc is the
 standard approach.  As of 2022, there are no recent reports of using
