According to config.log, configure script fails to detect libgcrypt as
following.

configure:24418: checking for gcry_check_version in -lgcrypt
configure:24443: c++ -o conftest -O2 -pipe -fstack-protector-strong -fno-strict-aliasing   -I/usr/local/include  -fstack-protector-strong  conftest.cpp -lgcrypt  -llzma -lbz2 -lz -ldl  >&5
ld: error: unable to find library -lgcrypt
c++: error: linker command failed with exit code 1 (use -v to see invocation)

The link error happens because '-L/usr/local/lib' is lacked from
options to compile conftest. And it is fixed by adding 'localbase' to
USES.

I'll submit patch to Bugzilla.
