One sensible solution would seem to be to set LD_LIBRARY_PATH_64=/usr/local/gcc-4.4.1-sun-linker/lib/sparcv9 on t2, but this actually doesn't seem to work. I'm not sure why.
However it seems that one can just add /usr/local/gcc-4.4.1-sun-linker/lib/sparcv9 to the LD_LIBRARY_PATH (it doesn't matter whether at the beginning or end) and this fixes the problems on t2. Shouldn't this be done globally for all users?
