That shared library was most likely built incorrectly (my guess is it was linked with ld -shared instead of gcc -shared (resp. g++ -shared, depending if it is C++ or C only lib)) or been created on really prehistorical systems (glibc 2.0.x). You can check that by running readelf -d /usr/local/vni/CTT3.0/lib/lib.linux/libimslcmath.so | grep NEEDED readelf -Ws /usr/local/vni/CTT3.0/lib/lib.linux/libimslcmath.so | grep __ctype_ If that's the case, the bug is on the ISV side. You can do workarounds for that (e.g. grab compat-glibc src.rpm from RHEL3, rebuild it on FC3 and link against that library (+ compile against its headers)), but preferrable is of course if the ISV fixes it.
