Note (probably harmless): No library found for -lgcrypt

libgcrypt must be installed prior to building Crypt::GCrypt and I can't 
find it in the standard library directories. You can download it from:

ftp://ftp.gnupg.org/gcrypt/libgcrypt/

and then you can install it just doing:
	$  ./configure
	$  make
	#  make install

If libgcrypt is installed, but in a non-standard directory, then use the
following options to Makefile.PL:

    GCRYPTLIBPATH=...  To set the directory in which to find libgcrypt
    GCRYPTINCPATH=...  To set the directory in which to find gcrypt.h

For example:
    perl Makefile.PL GCRYPTLIBPATH=/home/me/lib GCRYPTINCPATH=/home/me/include

Note that if you build against a shareable library in a non-standard location
you may (on some platforms) also have to set your LD_LIBRARY_PATH environment
variable at run time for perl to find the library.
