zef how dependencies of installed modules?

Hi All,

zef install File::Temp
===> Searching for: File::Temp
===> Searching for missing dependencies: File::Directory::Tree
...
Aborting due to test failure: 
File::Directory::Tree:ver<0.1>:auth<zef:labster> (use --force-test to 
override)

I did get this installed but I have a question about it.
After the module gets installed, how can I ask zef
what the dependencies were?  Me forgot and had to find
out the hard way.

Many thanks,
-T
