Help, dcc32 cannot find the bpl

[pe_la_do]

Hello,
I am trying to do a program that compiles from the command line, but I
have the following problem:

When I use to compile

search path := HKEY_CURRENT_USER\Software\Borland\Delphi\7.0\Library
\Search Path
dcc32 -Q -B -U"search path" dpr.name

I see the message "rtl not found"

but when I copy the whole content of the above mentioned folders
(*.bpl; *.dcp; *.dcu) to one folder (c:\tmp) compile OK
dcc32 -Q -B -U"c:\tmp" dpr.name

How I can do to compile without copying all the files to the same
folder ?
Already I tried modifying the files
name.dof
name.cfg
dcc32.cfg

Thank you in advance
