Summary: non-PIC library with all kde applications, prevents prelink from working

Description:   Opened: 2005-02-08 07:51 0000 
I tried to prelink my applications (as I have done in the past) to get them
load faster. Got hundreds of lines like this:

prelink: /usr/kde/3.3/bin/kmixctrl: Cannot prelink against non-PIC shared
library /usr/lib/libidn.so.11

I heard once that if prelink for one library fails it leaves the whole binary
non-prelinked (and thus slow). So, now none of my kde applications and such can
be prelinked? 

I had the things beautifully prelinked with no errors and just upgraded to use
~x86 and when I decided to prelink everything again, .. Any suggestions/fixes?

Reproducible: Always
Steps to Reproduce:
1. Use ~x86 arch with kde, libidn and stuff
2. Try to prelink the applications

Actual Results:  
Errors, most likely the process failed

Expected Results:  
Properly prelinked libraries..

Probably this is related to bug 72969.
Maybe the ebuild should just avoid passing any --with-pic or --without-pic 
option, after all libidn uses libtool and should do the right thing
automatically...

I don't understand all that, but I managed to recompile the library so that now
everything prelinks. (As suggested in that other bug report.)

I removed the pic flag form libidn. All should be ok now.
