I encounterd the same problem, after upgrading to Irix 6.2 I got a bunch
of linker warnings compiling and linking the perfly example. They look like
the following:
making IrisGL DSO version of perfly
        /usr/bin/cc -DIRISGL -DPFIRIX5 -I.. -I../../common
-I../../../../../../usr/include/ -nostdinc -I/usr/include -mips2 -o32 -O

Setting the LD_LIBRARY_PATH does not help any. The application is running
without fault, but I would still like to get rid of these warnings. Any idea
is welcomed.
