Well, that was certainly what I was thinking about. But I'm not
sure if it answers my problem (finding libraries which are
dlopen()'d when needed, instead of automatically loaded). But
perhaps I am either misunderstanding what ldd is telling me, or else
I have not looked at anything which does dlopen() libraries when
Scanelf seems to drop those libraries which are pulled in by the
libraries which a program uses, and that seems reason enough to use
it (for an editor).
Quick question: anyone know of any programs, or libraries, which
dlopen a library (ignoring PAM, which my searches found - I do not
build that) ?
What has prompted me to ask about this is TeX : it's always a pain!
When I last looked at it, something caused me to note that asy
(asymptote) needed ghostscript, and I marked that down as
dynamically opened. But there is no mention of this in my notes. I
suspect I got an error while trying to run asy on a system which did
not include ghostscript (for a short time I dropped ghostscript
because it was no longer needed for printing, but I reinstated it
because some other things in my desktop can use it).
But now, I cannot find references to ghostscript in either the
latest tl installer, or in the 2013 from-source version of TeX Live.
