[plt-scheme] Require pconvert.ss is extremely slow

Hi,

I use mzscheme on ppc405 (@266Mhz) embedded linux board, and doing a
require on pconvert.ss takes FOREVER. The same thing also happends on a
800Mhz P3 box in Win2K. 
On the ppc405, it takes a good 10 seconds.
On the Windows box it takes about 5-7 seconds just to load that 1 lib.
What could be the possible causes of this? On windows, I use
pre-compiled mzscheme from the installer. On the embedded side, I
compile it myself.

Thanks in advance.
