Steve,

First, keep in mind you need to set the CFG environment variable to
"debug" to get GDAL to build with debug info (ie. add -g to cflags).

Second, you can do "gdb .libs/nearblack" to use the actual executable
with the debugger.

Third, you can instead configure using --without-libtool and build
to avoid the libtool indirection shell scripts.
