[Sisyphus-incominger] E: incoming x86_64 reject: xfce4-panel-4.4.0-alt0.1

[Upravdom Team Robot]

Dear Eugene Ostapets !
The xfce4-panel-4.4.0-alt0.1 package has been rejected from incoming
for x86_64 architecture.

Possible reason follows:
checking for bind_textdomain_codeset... (cached) yes
checking for locales directory... /usr/share/locale
checking for additional xgettext flags... --keyword=Q_ --from-code=UTF-8
checking for X... libraries /usr/lib64, headers 
checking for gethostbyname... yes
checking for connect... yes
checking for remove... yes
checking for shmat... yes
checking for IceConnectionNumber in -lICE... yes
checking for main in -lX11... yes
checking for SmcSaveYourselfDone in -lSM... yes
checking for pkg-config... /usr/bin/pkg-config
checking for pkg-config >= 0.9.0... 0.21
checking for libxfce4util-1.0 >= 4.4.0... found, but 4.3.99.2
*** The required package libxfce4util-1.0 was found on your system,
*** but the installed version (4.3.99.2) is too old.
*** Please upgrade libxfce4util-1.0 to atleast version 4.4.0, or adjust
*** the PKG_CONFIG_PATH environment variable if you installed
*** the new version of the package in a nonstandard prefix so
*** pkg-config is able to find it.
