run-tests results on OS X mavericks

I installed gsll from quicklisp. I had to manually give values for the libgsl and libgslclas to get the install to work. Just to be sure it was installed correctly I ran the following:

CL-USER> (in-package :gsl) #<Package "GSLL"> GSL> (lisp-unit:run-tests) Unit Test Summary | 3983 assertions total | 3964 passed | 19 failed | 6 execution errors | 0 missing tests

#<TEST-RESULTS-DB Total(3983) Passed(3964) Failed(19) Errors(6)>

GSL> --

Are these results consistent with expectations or should I be getting no failures or execution errors?
