I try to use tcmalloc via export LD_PRELOAD="/usr/lib64/libtcmalloc.so". According to benchmarks, this should speedup one of my applications by 50%.

Unfortunately I get the following error:

ERROR: ld.so: object '/usr/lib64/libtcmalloc.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

I want to use it with an application installed in my home directory
