libIDL is an independently distributable component, but it's currently packaged _incorrectly_ with ORBit. REPEAT BY: trying to compile Mozilla M5 on a generic RedHat 6.0 distribution. SYMPTOM: Can't find the script identified above, so programs dependent on it can't link correctly. WORKAROUND: Get the source RPM for ORBit. Configure the "libIDL" package with "--prefix=/usr". Copy the resulting libIDL-config script into /usr/bin.
I find this marking of this a low priority to be somewhat of a problem. Mozilla is the next generation of web browsers to run on linux. Thanks for the work around but it strikes me that libIDL should be a separate package required by ORBit.
Has been fixed for a while
