>Description:
	
In index.c, it calls index_extract() for the depends of glib. Then,
finds perl is not installed, it asks to switch to disc1, after perl is
installed, the index_extract() of perl exists and return to execute the
original index_extract() of glib, at this time the disc volume has
already checked, but the disc has changed to disc1 in the CDROM, it
continue to execute the package_extract() part for glib, and unable to
find the glib package.

I think A quick fix for it is to put the volume checking part before 
the real install.

>How-To-Repeat:
sysinstall->Configure->Packages->CD/DVD->All->glib-2.8.6_1->Install->
This is disc #1. Package glib-2.8.6_1 is on disc #2
Would you like to switch discs now?

Yes->it installs gettext-0.14.5_2 and libiconv-1.9.2_2 , then says:

This is disc #2. Package Perl-5.8.8 is on disc #1
Would you like to switch discs now?

Yes->it installs perl-5.8.8 pkgconfig-0.20, and says:

Unable to fetch package glib-2.8.6_1 from selected media.
No package add will be done.
