Undefined aliens on CentOS 7

[hjudt]

When deploying woo in an centos7 container, i get these messages:

STYLE-WARNING: Undefined alien: "ev_default_loop_uc_"
STYLE-WARNING: Undefined alien: "ev_is_default_loop"
STYLE-WARNING: Undefined alien: "ev_loop"
STYLE-WARNING: Undefined alien: "ev_unloop"
STYLE-WARNING: Undefined alien: "ev_default_destroy"
STYLE-WARNING: Undefined alien: "ev_default_fork"
STYLE-WARNING: Undefined alien: "ev_loop_count"
STYLE-WARNING: Undefined alien: "ev_loop_depth"
STYLE-WARNING: Undefined alien: "ev_loop_verify"

and:
[14:04:14] woo.ev.tcp - Unexpected error (Code: 104)

Are there any constraints on the libev version? libev-4.15 is installed.
Apart from the error message, it seems to work fine.

I never tried, however, not surprising there’s some API differences with older libev.
Can you upgrade it to the latest version, 4.24? 4.15 was out 5 years ago.

For the record, I have upgraded to 4.24 and still get the style warnings and also the Unexpected error Code 104.
libev-devel.x86_64 4.24-alt1 installed
libev4.x86_64 4.24-alt1 installed
I also use the latest quicklisp dist.
