As Z. already mentioned, the "-uses" option only accepts a single unit name.
You will also need compiled units for

format-modular
args-support
srfi-37
csv

You also have to pass "-uses extras -uses srfi-1 -uses regex" (according to
the linker error you get).

Compiling units for the above mentioned eggs is somewhat tedious, but
something like to following should work:

# (example)
chicken args-support.scm -unit args-support -optimize-level 2 -debug-level 0

Since eggs are usually loaded in a dynamic fashion, you will also need
to "provide" some features to avoid that dynamic loading. For example
"args" does a "require-extension" of "srfi-37", which can be avoided by
compiling args-support.scm with "-prelude '(provide (quote srfi-37))' and
doing the "-uses srfi-37" on the command-line of the main executable.

It's all quite messy, I agree. But if you run into any problems, just state
exactly what eggs you need and I will provide you with the necessary
incantations.

Also, since you compile with full optimization options for gcc, you might
also want to enable optimization for Scheme files (for example by
passing "-optimize-level 2 -debug-level 0").
