Your private key is encrypted with CAST5 but you have disabled support
for CAST5 in gpg or you disabled CAST5 when you built libgcrypt.

> gpg (GnuPG) 2.0.14
> libgcrypt 1.4.5

[These are 8 year old versions.  You should not use such old versions.]

 Pubkey: RSA, ELG, DSA
 Cipher: 3DES, AES, AES192, AES256

Yep: No support for CAST5 - this is not the default.  Rebuild Libgcrypt
w/o disabling algos and while you do that you should move to a supported
versions, best 1.8.0.


Salam-Shalom,
