relocation error: nimage_c.so: undefined symbol: str2cstr

[ara howard]

rubyists-

i've compiled the ruby narray and nimage packages and am attempting to run one
of the demo programs but keep getting these types of errors:

ruby: relocation error:
/data/ruby-1.8.0//lib/ruby/site_ruby/1.8/i686-linux/nimage_c.so: undefined
symbol: str2cstr

now, it's been while since i did any ruby/c bindings, but shouldn't this
symbol be available in any running ruby program? an ldd of the lib shows

libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40020000)
libdl.so.2 => /lib/libdl.so.2 (0x400f6000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x400f9000)
libm.so.6 => /lib/i686/libm.so.6 (0x40126000)
libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

so it would seem that it is, in fact, expecte that str2cstr should be found
withing the libs loaded by ruby itself. has this method vanished or something?
