source navigator启动报错

今天在 ubuntu12.04下安装source navigator，编译安装完成后，启动报错，信息如下：

migw@migw-Zhaoyang-E49:/opt/sourcenav/bin$ ./snavigator 
Can't find a usable tk.tcl in the following directories: 
    /opt/sourcenav/share/tk8.3

/opt/sourcenav/share/tk8.3/tk.tcl: no event type or button # or keysym
no event type or button # or keysym
    while executing
"bind Listbox  {
    %W yview scroll [expr {- (%D / 120) * 4}] units
}"
    (file "/opt/sourcenav/share/tk8.3/listbox.tcl" line 182)
    invoked from within
"source [file join $tk_library listbox.tcl]"
    invoked from within
"if {[string compare $tcl_platform(platform) "macintosh"] && \
	[string compare {} $tk_library]} {
    source [file join $tk_library button.tcl]
    so..."
    (file "/opt/sourcenav/share/tk8.3/tk.tcl" line 308)
    invoked from within
"source /opt/sourcenav/share/tk8.3/tk.tcl"
    ("uplevel" body line 1)
    invoked from within
"uplevel \#0 [list source $file]"


This probably means that tk wasn't installed properly.

网上查了下，有人提出方案：

註掉 lines 182-184 in the file /opt/sourcenav/share/tk8.3/listbox.tcl
註掉 lines 457-459 in the file /opt/sourcenav/share/tk8.3/text.tcl

试下，启动成功！
