I do not have yum too :/
In fact as i said, i have a NAS Synology CS407 and then the OS is DiskStation Manager(DSM). It's a bit particular. I had retrieved a bootstrap in order to have ipkg and it's all i have.
So i think the only things that i can do in addition to that is to ./configure, make and makeinstall. Recently, I've added autoconf and automake, but it's all.
If i can install apt-get or yum, it would be nice.
