srfi-19 uses srfi-29 uses lookup-table. The "srfi-29.meta" file does  
state the need for lookup-table, so I wonder why it is not installed.  
How old is your copy of srfi-29? The need for lookup-table is from  
version 1.2, quite awhile ago.

In any case current srfi-19 1.9 needs srfi-29 1.5 needs lookup-table  
1.2, the current releases. Suggest installing from the eggs repo.

You might as well also get the current locale, miscmacros, numbers, &  
misc-extn eggs. These are also needed.

FWIW, w/ the most recent Chicken, newer than 2.422, you should also  
have the easyffi & dollar eggs, at least for my stuff.

Hope you have a more productive time after re-installing.

Best Wishes,
Kon
