system libs are searched by default so having RPATH to them seems like
asking for trouble.

People how set paths by ldconfig and LD_LIBRARY_PATH get the results
they ask for.  I wouldn't worry about them, absent a good argument for
why some particular setup is rational.

What I meant to say is that I don't understand where that RPATH setting
is coming from in the build, which is probably deep in bl3 files and
wrappers.   I suggest enough tracing to figure out where it is coming
from and why, and then evaluating whether that is buggy.  Right now  we
just don't know.

This seems really awkward, compared to option 2.  Before doing this, I
think we should have a really clear understanding of what is going on.


Option 4 is to figure out why pkgsrc liblzma is ever built on this
system, when the base system version is adequate.  Basically we need to
have a consistent decision about good enough or not good enough, and
this is generally true about bhiltin detection.  We have had cases where
base had version X and that was good enough for some things but other
things needed X+1 and pulled in pkgsrc.  This went really badly and we
resolved it by making builtin detection require a version that was
generally good enough, not just for the current program, but anything
normal.

Why is the library installed in pkgsrc?  What if you pkg_delete that?
If something depends on that, why doesn't it use the base version?


I am assumign that you have not changed the base system during all
this.  (If you did, the answer is don't do that!)
