Looks like there are some typos in the wp-slim package's .info file. I've fixed them. If you're installing from CVS, just
cvs update
to get the fixed code.
Otherwise, go into the file packages/wp-slim/wp-slim.info
3 lines in this file are missing the closing bracket (>). Add the closing bracket to lines 148, 227 and 230. This should fix it.
Thanks for pointing this out.
