how to compile with popt lib?

This is hopefully a simple question but after 90 minutes of googling, forum and man page perusal, I'm having a difficult time compiling an example popt program. I'm currently using the example code provided in Maverick's "$ man popt", and receiving this error:

$ gcc -o popt_test popt_test.c
popt_test.c: In function ‘main’:
popt_test.c:32: warning: passing argument 3 of ‘poptGetContext’ from incompatible pointer type
/usr/include/popt.h:261: note: expected ‘const char **’ but argument is of type ‘char **’

popt_test.c:(.text+0x38c): undefined reference to `poptBadOption'
popt_test.c:(.text+0x490): undefined reference to `poptFreeContext'
collect2: ld returned 1 exit status

I've tried to link against the object files I /think/ it's missing, namely directly adding -l/lib/libpopt.so.0 to the gcc line, but I'm having no love. Have I perhaps overlooked a necessary apt-get?
