This symbol is defined in libc.so.5.  One way you can see this problem
is if you are running a 4.x binary that links to libm.so.2 on a 5.x
system, because libm has the same version number in 5.x but is not
binary compatible.  So the 4.x binary links to libc.so.4 and
libm.so.2, and the latter is actually a 5.x library that expects to
have __fpclassifyd resolved by linking with libc.so.5.  Is it the case
on your system that you have old 4.x binaries installed?
