more libedit.so.0 issues

[James Swaine]

it says:

libedit.so.0 => not found
    libncurses.so.5 => /usr/lib64/libncurses.so.5 (0x00000039e2200000)
    libutil.so.1 => /lib64/libutil.so.1 (0x00000039dba00000)
    libdl.so.2 => /lib64/libdl.so.2 (0x00000039cfc00000)
    libm.so.6 => /lib64/libm.so.6 (0x00000039cf800000)
    libgmp.so.3 => /usr/lib64/libgmp.so.3 (0x00000039d5800000)
    librt.so.1 => /lib64/librt.so.1 (0x00000039d3800000)
    libpthread.so.0 => /lib64/libpthread.so.0 (0x00000039d0000000)
    libc.so.6 => /lib64/libc.so.6 (0x00000039cf400000)
    /lib64/ld-linux-x86-64.so.2 (0x00000039cec00000)

i noticed that my PATH variable doesn't include /usr/local/lib, do you think
this might be the problem?
