>Description:
Currently irc/eggdrop requires Tcl 8.4 which is wrong because eggdrop works just as good with other Tcl versions. If your system has (for example) Tcl 8.5 only, irc/eggdrop will install 8.4 instead of using 8.5. The attached patch changes the Makefile to use the bsd.tcl.mk functions to determine the newest installed Tcl version and point the eggdrop configure script to the appropriate files. I set the minimum required Tcl version to 8.0 (the smallest possible value) since the configure only requires 7.0.

I also removed the manual setting of the build target because it results in exactly the same as compared to having the ports system automatically set it. I assume, it's better to use the provided value in case of future changes.
If this was set on purpose to circumvent a problem in other environments, you should not include this change.
>How-To-Repeat:
pkg_delete tcl84
cd /usr/ports/irc/eggdrop
make clean && make
>Fix:
cd /usr/ports/irc/eggdrop && patch -p1 < patch.txt
