poudriere: success(?) despite "ELF interpreter /lib/ld-linux.so.2 not found, error 2"?

Sat Feb 13 15:24:08 UTC 2016

I encountered an unexpected whine-like message during a poudriere
run, but it doesn't seem to actually have indicated a reported (or
logged) error.  So I wrote this up, hoping for a reality check.

I started using poudriere to build my own packages for my stable/10
amd64 machines last July (and actually started installing those
packages on a couple of the machines shortly thereafter).  That
effort appears to have been reasonably successful: one of the
machines thus affected is the one where this email message is being
created; the other is the machine that acts as a packet filter
between the Internet and my internal networks at home.

I update those machines weekly (Sunday mornings) -- first FreeBSD
base, then the installed packages.  In order to accomplish that, I
update FreeBSD base on a "build machine," and perform a "poudriere
bulk" on the same build amchine.  (Actually, I do a couple "poudriere
bulk" runs: one Saturday morning, after the Saturday update to
FreeBSD on the build machine, and another on Sunday, after the
update that day.  The intent is to reduce the amount of package-building
time required on Sunday.)

I perform all FreeBSD builds and poudriere runs within script(1), as I
like to have a record of what happened.

This morning, I just happened to glance at the xterm where poudriere
was running, and noticed a message I wasn't expecting:

ELF interpreter /lib/ld-linux.so.2 not found, error 2

I wondered a few things at that point, including:
* What port it was working on when that was issued?
* Does that (message) indicate a failure to build a package?
* Has it been issued before?

Eventually, the poudriere run ended:

...

freebeast(10.3)[2] echo $?
0

I suppose that answers the 2nd of my questions (above) in the negative.

And looking through the poudriere typescripts, I found that the
message was also issued 31 January -- again with no (other) indication
of error:

...

freebeast(10.3-P)[2] echo $?
0
freebeast(10.3-P)[3] exit

(I only keep the last 4 poudriere typescripts, unless I have some
reason to retain one specially.)

I then checked /usr/local/poudriere/data/logs/bulk/10amd64-ports-home:

freebeast(10.3)[9] dirs
/usr/local/poudriere/data/logs/bulk/10amd64-ports-home 
freebeast(10.3)[10] grep -r 'ELF interpreter .* not found' .
freebeast(10.3)[11] echo $?
1
freebeast(10.3)[12] 

Mind, I haven't got around to cleaning out my logs yet, so I have
all of them since I started using poudriere:

freebeast(10.3)[13] 

So we can conclude that the message has been issued before, but I
have no evidence to tie its issuance with the build of any particular
package.  Since the packages all report having been built OK, I suppose
nothing is exactly wrong, per se... but this seems a little on the "odd"
side.

I use private SVN mirrors of the FreeBSD src, ports, and doc
repositories, updated nightly (in 2 stages, for historical reasons
dating back to CVS and CVSup & inertia on my part).
