i'm guessing you have more that one ruby installs on your system and compiled
without setting LD_RUN_PATH or LD_LIBRARY_PATH.

for any c code you compile you always want to consider these two env vars and
their effect on ld.so.

if installing into /usr/local/bin you'd want to do this

   export LD_RUN_PATH=/usr/local/lib
   export LD_LIBRARY_PATH=/usr/local/lib

   ./configure --prefix=/usr/local && make && sudo make install

   export PATH=/usr/local/bin:$PATH

and ruby should work.  to confirm that this might be your problem try

   which -a ruby

if you see two the above is likely.  man ld.so.conf or google
LD_RUN_PATH/LD_LIBRARY_PATH for more.

this is incomplete, but it might shed some light
