但是在终端中通过"$snavigator"指令启动sourcenavigator时，出现如下问题：

 1 Can't find a usable tk.tcl in the following directories: 
 2     /usr/local/share/tk8.3
 3  
 4 /usr/local/share/tk8.3/tk.tcl: no event type or button # or keysym
 5 no event type or button # or keysym
 6     while executing
 7 "bind Listbox <MouseWheel> {
 8     %W yview scroll [expr {- (%D / 120) * 4}] units
 9 }"
10     (file "/usr/local/share/tk8.3/listbox.tcl" line 182)
11     invoked from within
12 "source [file join $tk_library listbox.tcl]"
13     invoked from within
14 "if {[string compare $tcl_platform(platform) "macintosh"] && \
15     [string compare {} $tk_library]} {
16     source [file join $tk_library button.tcl]
17     so..."
18     (file "/usr/local/share/tk8.3/tk.tcl" line 308)
19     invoked from within
20 "source /usr/local/share/tk8.3/tk.tcl"
21     ("uplevel" body line 1)
22     invoked from within
23 "uplevel \#0 [list source $file]"
24  
25  
26 This probably means that tk wasn't installed properly.

然后google，看了看，知道解决方法了。

注意上面的第10行：file “/usr/local/share/tk8.3/listbox.tcl” line 182
于是：
$sudo gedit /usr/local/share/tk8.3/listbox.tcl
注释掉182~184三行。

然后：
$snavigator
又囧了，提示如下：

 1  
 2 Can't find a usable tk.tcl in the following directories: 
 3     /usr/local/share/tk8.3
 4  
 5 /usr/local/share/tk8.3/tk.tcl: no event type or button # or keysym
 6 no event type or button # or keysym
 7     while executing
 8 "bind Text <MouseWheel> {
 9     %W yview scroll [expr {- (%D / 120) * 4}] units
10 }"
11     (file "/usr/local/share/tk8.3/text.tcl" line 457)
12     invoked from within
13 "source [file join $tk_library text.tcl]"
14     invoked from within
15 "if {[string compare $tcl_platform(platform) "macintosh"] && \
16     [string compare {} $tk_library]} {
17     source [file join $tk_library button.tcl]
18     so..."
19     (file "/usr/local/share/tk8.3/tk.tcl" line 308)
20     invoked from within
21 "source /usr/local/share/tk8.3/tk.tcl"
22     ("uplevel" body line 1)
23     invoked from within
24 "uplevel \#0 [list source $file]"
25  
26  
27 This probably means that tk wasn't installed properly.

照着葫芦画瓢，注意第11行：file “/usr/local/share/tk8.3/text.tcl” line 457

好吧：
$sudo gedit /usr/local/share/tk8.3/text.tcl
注释掉457~459行。
然后再：
$snavigator
正常了。
