you can try also directly editing /var/lib/sbopkg/SBo/13.1/libraries/libixp/libixp.info substituting the line
Code:
DOWNLOAD="http://code.suckless.org/dl/libs/libixp-0.4.tar.gz"
with
Code:
DOWNLOAD="http://dl.suckless.org/libs/libixp-0.4.tar.gz"
you will have to do the same thing with wmii editing /var/lib/sbopkg/SBo/13.1/desktop/wmii/wmii.info, substituting
Code:
DOWNLOAD="http://code.suckless.org/dl/wmii/wmii-3.6.tar.gz"
with
Code:
DOWNLOAD="http://dl.suckless.org/wmii/wmii-3.6.tar.gz"
then it should build fine.
obviously when you sync again with sbopkg you will lose these modifications
EDIT: slakmagik posted the same thing while I was writing
you will find the maintainer email in the same info file.
