James, 

Thanks for the massive reply (I get the feeling you've been asked this
question before.) I set LD_LIBRARY_PATH as you suggested and tried to
recompile sqsh version 2.1. This time gcc gags as follows:

/opt/sybase/lib/libintl.so: undefined reference to `__ctype_b'
collect2: ld returned 1 exit status
make[1]: *** [sqsh] Error 1
make[1]: Leaving directory `/usr/src/sqsh-2.1.3/src'
make: *** [build-subdirs] Error 2

Clueless as usual, I wonder if you've seen THAT before. If it is still
the linker, I don't know where else to tell it to look.

Thanks,

James
