Hello,

I'm trying to build the sysutils/dar port with the GCRYPT option 
enabled. During he configure stage, I see:

checking for gpg_err_init in -lgpg-error... no
checking for gcry_check_version in -lgcrypt... no
checking gcrypt.h usability... yes
checking gcrypt.h presence... yes
checking for gcrypt.h... yes
checking for libgcrypt usability... failed: need libgcypt >= 1.4.0, 
disabling strong encryption support

And yet:

# pkg info|grep gcrypt
libgcrypt-1.9.4_1              General purpose cryptographic library 
based on the code from GnuPG

This is on 13.1-stable as of a week ago.

Does anybody have any clues, please?

Thanks,
