[xmlsec] error compiling from buildroot

[sred_94 at libero.it]

Dear Sirs, I have tried to compile xmlsec through Buildroot, but the compilation ended with this error:
checking for gnutls libraries >= 2.8.0... configure: error: xmlsec-gnutls library requires xmlsec-gcrypt library which is disabled or missing

How can I overcome this problem?

Thanking you in advance,
Simone Rossi
