Compile error: 3.1.6

[Ken_Shelby@xxxxxxxxxxxxxxxxx]

I'm running Squid 3.1.4 on Fedora 13, and all is well. 

I grabbed a copy of Squid 3.1.6 and tried to compile it, but ran into an 
error.  To my novice eye it looks like I somehow botched a file path.  The 
"configure" script ran with no issues.  Here are all of the options I used 
with it  (identical to the ones I used with 3.1.4) :

    $ ./configure --enable-dlmalloc --enable-linux-netfilter 
--enable-storeio=ufs,aufs --with-aio-threads=16

Here are the last few lines of compiler output, with the error:

    ...

    make[1]: Leaving directory `/usr/local/src/squid/squid-3.1.6/src'
    make: *** [all-recursive] Error 1

This is what I find on the machine:

    [root@XXXXXXXX /]# find / -type d -name 'libltdl'
    /usr/local/src/squid/squid-3.1.6/libltdl
    /usr/local/src/squid/squid-3.1.6/libltdl/libltdl
    /usr/local/src/squid/squid-3.1.4/libltdl

It seems that the "lt_error.h" file expects "lt_system.h" to be in the 
immediate parent directory, but they are both in the same directory.  How 
did I do that?!?!   Here is the line in "lt_error.h" : 

    #include <libltdl/lt_system.h>

Anyway, I seem to have created a functional kludge by putting a soft link 
in the "/usr/local/src/squid/squid-3.1.6/libltdl" directory, like this:

    lrwxrwxrwx 1 root root     21 Aug  2 16:48 lt_system.h -> 
./libltdl/lt_system.h

Thanks!
