Yes, your solution probably removes perl from %PATH% after the BEGIN block. I can think of two reasonable answers at the moment: (both untested)
- Move use Tcl; into the BEGIN block and use local when adjusting $ENV{PATH}.
- Prepend the Tcl directory to the PATH with $ENV{PATH} = $pathTclBin . ';' . $ENV{PATH}; instead of replacing PATH. (The PATH separator is colon on POSIX and semicolon on Windows.)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
