This is not the reason. If it picked up the wrong library, then there would be a 
message that there was the wrong ELF class, but no library whatever is being found.

I've tried without the 'sparcv9' in LD_LIBRARY_PATH and it makes no difference 
whatsoever. I've tried on two SPARCs too, running different releases of Solaris 10.

Using 'crle' might work, but that is not really a good answer, as it needs root 
access. It should be possible to install an application like R without being 
root. There is something wrong if LD_LIBRARY_PATH can't be used to locate 
libraries.

I can build the whole of the Sage source code (around 300 MB) and don't see this 
failure elsewhere. Instead, there are a number of programs which link to 
libgcc_s.so.1.

I stuck some further information at

http://trac.sagemath.org/sage_trac/ticket/9201

but it basically just confirms what I've written above.
