[gentoo-dev] emerge of qt3.0.4.1 doesn't work + solution

[Wido Depping]

The emerge of qt3.0.4.1 stops at this point:

make[3]: Entering directory

make[3]: *** [../../../bin/uic] Error 1

As the error message indicates, liblcms.so.1 isn't found. But it is installed 
on my system. So I had a look at /usr/lib:

lrwxrwxrwx    1 root     root           12 May  2 16:09 liblcms.so -> 
liblcms.so.1
-rwxr-xr-x    1 root     root       109400 May  2 16:09 liblcms.so.1.0.8

As you can see, there is missing a symbolic link since liblcms.so points to a 
non-existing file. So I created a link from liblcms.so.1.0.8 to liblcms.so.1 
and now everything works fine.
This problem prevented me also from compiling KDE from cvs.
