checking for GDU_MODULE_VERSION_CHECK... configure: error: Package requirements (gnome-doc-utils >= 0.3.2) were not met: Requested 'gnome-doc-utils >= 0.3.2' but version of gnome-doc-utils is 0.2.1 Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GDU_MODULE_VERSION_CHECK_CFLAGS and GDU_MODULE_VERSION_CHECK_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.

Thanks for reporting this problem. sound-juicer depends on >=gnome-doc-utils-0.3.2 since version 2.12.3. This has been corrected in the ebuild.
