(this is in relation to earlier fixed undefined PLT symbol problem in ld.)

I am having a problem,
we are running netbsd on our product, it is having a memory based file

I verified that if on my build machine / standalone machine, if I just
expand the base.tgz over the 1.6.1 installation we were currently having.
programs compiled beforehand are running properly.

But, due to some limitations I cannot release / expand all the files in
this released label (of base.tgz )by the author,
I just updated ld.elf_so over the current /usr/libexec and any program
started after this is hanging !
I wrote a simple printf("Hello world \n") and even that is hanging.

Could somebody provide some direction to is ld.elf_so good enough for this
fix ? or do I need to replace something else also ??
Are libs (/usr/libs) also needed to be updated ?? I will put those also,
but why should these be needed.
as from what I understand, ld.elf_so should just be using the info from the
libraries and map them, has some change been done in their stucture also ..
reason for asking this is that our system also has some dynamically linked
libararies built, so we will have to rebuild those also ??

Could some body please explain as to what / how was this fix done. so that
people like me can have a better idea in a situation like I am to make
debugging time least.

there's got to be some file in base.tgz which made things work fine on
standalone netbsd pc ..

( We are having an i386 build, if it will matter. )

No there shouldn't be any.

Yes, it should be possible

Or you can just use the ld.elf_so from the 1.6.2 distribution.

But I'm not sure this is fixed in 1.6.2. I had to use a current ld.elf_so
on my alpha to get rid of this. The current ld.elf_so is fine on my 1.6.2
alpha, but I don't know how it would be on i386.
