Well, it would be nice to have exact bug report if you see some problem,
please test current git version.

The  --disable-kernel_crypto switch is required only for systems where
kernel with userspace crypto API will never be available.

For other systems it is maintainer's job to set up dependences properly
(require proper kernel headers).

FYI: you will see this warning (RHEL5, as example of old system)
...
checking for linux/if_alg.h... no
configure: error: You need Linux kernel headers with userspace crypto interface. (Or use --disable-kernel_crypto.)

Here (RHEL5) the only option is to use --disable-kernel_crypto.
