ldd says “not found” even though library is in my LD_LIBRARY_PATH

Question

$ ldd libpmsfdcwrt.so
        linux-gate.so.1 =>  (0x004ae000)
        libdl.so.2 => /lib/libdl.so.2 (0x00417000)
        [ ... elided ... ]
        libz.so.1 =>         


        

Answer 1

The problem was a 32-bit/64-bit collision:

$ file libpmsfdcwrt.so
libpmsfdcwrt.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, not stripped

$ file /lib64/libz.so.1.2.3
/lib64/libz.so.1.2.3: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped

Thank you, everyone, for pointing me in the correct direction.
