The krb5-config in 1.4.1 will use the RPATH_FLAG as set from configure.
So if you use the same compiler and linker as used to built the krb5 libs
it should be able to handle "-R" or the "-Wl,-rpath -Wl,"

I did make one change in this area which makes it much easier when building,
so that the -L used during building, does not have to match the -R
that would be used when in production. The environment variable
KRB5INAFS can be set to point to the location of the libs duing building.

FOr example whien building OpenSSH, setting
KRB5INAFS="/afs/my.cell/build.appls/krb5-1.4.1/@sys"

With the prefix set to /krb5 will cause:
./krb5-config --libs
-L/afs/my.cell/build.appls/krb5-1.4.1/@sys/krb5/lib -R/krb5/lib
   -lkrb5 -lk5crypto -lkrb5support -lcom_err -lresolv -lsocket -lnsl
