Comment (by dimpase):

 here are more details; without optional GMP package installed, one still
 gets 4ti2gmp built by doing `sage -i 4ti2`; its linkage is as follows:
 {{{
 $ ldd local/bin/4ti2gmp
         linux-vdso.so.1 =>  (0x00007fffd2179000)
         lib4ti2gmp.so.0 =>
 /home/dima/software/sage.6.6/sage/local/lib/lib4ti2gmp.so.0
 (0x00007f5ff4cc7000)
         libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6
 (0x00007f5ff49a8000)
         libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1
 (0x00007f5ff4791000)
         libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f5ff43cc000)
         libglpk.so.36 =>

         libgmpxx.so.8 =>
 /home/dima/software/sage.6.6/sage/local/lib/libgmpxx.so.8
 (0x00007f5ff3eee000)
         libgmp.so.16 =>
 /home/dima/software/sage.6.6/sage/local/lib/libgmp.so.16

         libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f5ff3974000)
         /lib64/ld-linux-x86-64.so.2 (0x00007f5ff4f4e000)
         libz.so.1 => /home/dima/software/sage.6.6/sage/local/lib/libz.so.1
 (0x00007f5ff3759000)
 }}}
 it looks as it is linked against GMP, but this is just a differently named
 copy of MPIR.
