So it must have been using the static libs when it linked.
If you still have the old binary around you can run nm on it and look 
for the references to the functions you are interested in. In this case 
pcre.

nm hobbitd |grep -i pcre
[289]   |    248184|       0|FUNC |GLOB |0    |UNDEF  |pcre_compile
[228]   |    248196|       0|FUNC |GLOB |0    |UNDEF  |pcre_exec
[480]   |    255612|       4|OBJT |GLOB |0    |22     |pcre_free


In this case the hobbitd binary has UNDEF for the routines with pcre. 
The system linker/loader would have to resolve these by using external 
libs such as the .so versions of the lib or the binary is a no-go.
Any statically linked routines wouldn't have UNDEF.
