This is my Bpl:

unit GlobalUnit;


interface
uses ExtCtrls, Buttons;
//procedure vcPanelResize(Sender: TObject);

implementation

procedure vcPanelResize(Panel:TPanel);
var
  i,m,n:integer;
begin
  m:=1; n:=1;
  for i:=0 to Panel.ControlCount-1 do
    begin
      if Panel.Controls[i].ClassType=TBitBtn then
        begin
          with Panel.Controls[i] as TBitBtn do
            begin
              Top:=m;
              Left:=n;
              Width:=Panel.Width-2;
              m:=m+Height+1;
            end;
        end;
    end;
end;

exports
vcPanelResize name 'vcPanelResize';

end.

How can I call procedure vcPanelResize from my main program.

something like this:
uses GlobalUnit;

....
vcPanelResize(apanel);
make sure that the bpl is in the path of the program (can be current dir). for compiling, make sure tha bpl is in the lib path of the project

I never wrote a bpl :D (I know, some ppl might remain ... "amazed" (can't find the right word))
I'll do that in a few minutes and let you know my findings

I found this article: http://delphi.about.com/od/objectpascalide/l/aa010901c.htm
following it, I created a test app and run it just fine.

what I have done is:
unit Unit1;

interface

procedure test;

implementation

uses dialogs;

procedure test();
begin
  showmessage('test');
end;

exports
  test name 'test';

end.

in package1. changed in project p[roperties to output in current dir. compiled. installed. then created a test app:

unit bla;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs;

type
  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

uses unit1;

procedure TForm1.FormCreate(Sender: TObject);
begin
  test;
end;

end.

open project settings, go to packages, check build with runtime packages and add "package1".
compile.
copied bpl file to the exe dir and run exe. message was shown.

in your case: uncomment:
interface
uses ExtCtrls, Buttons;
//procedure vcPanelResize(Sender: TObject);

and make sure you followed the aboe steps.

well ... that is what build with runtime packages mean. I thought you know. the best solution is not to use runtime packages, I don't know of any way to use partly runtime packages, partly design packages. if you want to have some code "outside" and some compiled into the exe, then you will have to use dll's. there is no other way, AFAIK.
