After a bit of digging, I found some more details.

Should anyone be interested, it appears that the -R
flag is bogus under AIX (with the possible exception
of AIX 5.3 where another compatibility flag needs to
be set).

So, I noticed a couple of lines in
pkgsrc/mk/platform/Darwin.mk:
_OPSYS_LINKER_RPATH_FLAG=       -L
_OPSYS_COMPILER_RPATH_FLAG=     -L

So, I added those lines to pkgsrc/mk/platform/AIX.mk,
and my builds stopped complaining about "ignoring -R
flag".

Does anyone have a good reason why this shouldn't be
changed by default to this value?
