This would appear to be a common problem with many other packages
using dlopen like pam.
dlopen man page says:
If filename contains a slash ("/"), then it is interpreted as a
(relative or absolute) pathname. Otherwise, the dynamic linker
searches for the library as follows (see ld.so(8) for further details):
So can the default be just "libpcsclite.so"?
