Since there is no error message '/usr/bin/ld: cannot find -lhtcobol',
then it must be another version of the TC RTL, not version 0.63.87.

Check the 'develoment/lib' directory to see if the RTL compiled properly
(check for a file called libhtcobol.a).
If the library file exists, run the following, manually.

#htcobol -v -c /TinyCat/DEGRABBER.COB
as -o DEGRABBER.o DEGRABBER.s
#gcc -o DEGRABBER DEGRABBER.o -L/somepath/development/lib -lhtcobol \
   -ldb -lncurses -ldl -lm

Here the 'somepath' is the location where the TC source code is located.

If the compilation succeded, check that all libraries are found.

#ldd DEGRABBER

All RPM based sytems have multiple versions of BDB installed.
They also use soft links, making it difficult to determine which library 
is actually used when '-ldb' is used in a link step.

TC uses the BDB 1.85 API, which is supported in all versions of BDB, up 
to (and including) 4x (4.4 I think).

In any case the 'configure' script checks what is installed and if it 
works.
So if the 'configure' step worked, don't worry about it for the time being.

Hope this helps.

Cheers
