[Upravdom Team Robot]

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

Possible reason follows:
checking for perl... /usr/bin/perl
checking for XML::Parser... ok
checking for iconv... /usr/bin/iconv
checking for msgfmt... /usr/bin/msgfmt
checking for msgmerge... /usr/bin/msgmerge
checking for xgettext... /usr/bin/xgettext
checking what sound system to use... oss
checking for _oss_ioctl in -lossaudio... no
checking for pkg-config... /usr/bin/pkg-config
checking for pkg-config >= 0.9.0... 0.21
checking for libxml-2.0 >= 2.4.0... 2.6.27
checking XML_CFLAGS... -I/usr/include/libxml2  
checking XML_LIBS... -lxml2  
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.
