You can use the following set of commands to verify that the package has been installed and your environment is setup such that you can find the xml-keyval commands within your path:

[pkb@salsa pkb]$ mkdir $HOME/bogus
[pkb@salsa pkb]$ cd $HOME/bogus
[pkb@salsa bogus]$ keyval2sh --name spellcheck --doc-type none
creating template file: spellcheck_config.xml
Generating: spellcheck_config.sh
Generating: spellcheck_config.docbook_synopsis
Generating: spellcheck_config.docbook_options
Creating Template: spellcheck.sh
Creating Template: spellcheck.mk
Creating Template: spellcheck.docbook
Finished - finally!
STEP 1: Try invoking:
  make -f spellcheck.mk; ./spellcheck --help
STEP 2: Then edit files:
  spellcheck.sh, spellcheck_config.xml and spellcheck.docbook
STEP 3: Repeat steps 1 and 2 until life is good.
[pkb@salsa bogus]$ make -f spellcheck.mk
cat "spellcheck_config.sh" "spellcheck.sh" > "spellcheck"
chmod +x "spellcheck"
[pkb@salsa bogus]$ ./spellcheck.sh

If you don't see output similar to the above, you'd better go through the Installation Guide chapter from top to bottom (getting your Java environment set properly can be a bit tricky).
